Summary:
Currently, only `Text` supports the `allowFontScaling` prop. This commit adds support for it on `TextInput`.
As part of this change, the TextInput setters for font attributes (e.g. size, weight) had to be refactored. The problem with them is that they use RCTFont's helpers which create a new font based on an existing font. These helpers lose information. In particular, they lose the scaleMultiplier.
For example, suppose the font size is 12 and the device's font multiplier is set to 1.5. So we'd create a font with size 12 and scaleMultiplier 1.5 which is an effective size of 18 (which is the only thing stored in the font). Next, suppose the device's font multiplier changes to 1. So we'd use an RCTFont helper to create a new font based on the existing font but with a scaleMultiplier of 1. However, the font didn't store the font size (12) and scaleMultiplier (1.5) separately. It just knows the (effective) font size of 18. So RCTFont thinks the new font has a font size of 18 and a scaleMultiplier of 1 so its effective font size is 18. This is incorrect and it should have been 12.
To fix this, the font attributes are now all stored individually. Anytime one of them changes, updateFont is called which recreates the font from scratch. This happens to fix some bugs around fontStyle and fontWeight which were reported several times before: #13730, #12738, #2140, #8533.
Created a test app where I verified that `allowFontScaling` works properly for `TextInputs` for all values (`undefined`, `true`, `false`) for a variety of `TextInputs`:
- Singleline TextInput
- Singleline TextInput's placeholder
- Multiline TextInput
- Multiline TextInput's placeholder
- Multiline TextInput using children instead of `value`
Also, verified switching `fontSize`, `fontWeight`, `fontStyle` and `fontFamily` through a bunch of combinations works properly.
Lastly, my team has been using this change in our app.

Summary:
Nothing behavioral changed in this diff; just moving code around.
`RCTBackedTextInputDelegate` is the new protocol which supposed to be common determinator among of UITextFieldDelegate and UITextViewDelegate
(and bunch of events and notifications around UITextInput and UITextView).
We need this reach two goals in the future:
* Incapsulate UIKit imperfections related hack in dedicated protocol adapter. So, doing this we can fix more UIKit related bugs without touching real RN text handling logic. (Yes, we still have a bunch of bugs, which we cannot fix because it is undoable with the current architecture. This diff does NOT fix anything though.)
* We can unify logic in RCTTextField and RCTTextView (even more!), moving it to a superclass. If we do so, we can fix another bunch of bugs related to RN imperfections. And have singleline/multiline inputs implementations even more consistent.

Summary:
Motivation:
* We maintain two different implementation of <TextInput> (multilined and singlelined), this change makes the implementations much similar which will help us to support and improve both of them in the (near) future;
* We have to have separated RCTView-based container view for (TextField) to support sofisticated bordering and so on;
* It opens to us possibility to unify UITextView and UITextField subclasses and remove code duplication across RCTTextView and RCTTextField;
* Making things decoupled in general will allow us to fix existing bugs with events.

Summary:
Singleline <TextInput> now has intrinsic size which is equal to size of placeholder.
And if <TextInput> does not have placeholder it still has intrinsic height.
So, we don't need to set the size up manually every single time anymore!
(Multiline <TextInput> already has this feature.)

Summary:
This exposes iOS's spellCheckingType functionality to JavaScript. The native functionality is a three state enum. It gets exposed to JavaScript as a boolean. The initial value and JS null map to the third state.
An alternative design for this API would have been to expose a three state enum to JavaScript:
- "on" which maps to UITextSpellCheckingTypeYes
- "off" which maps to UITextSpellCheckingTypeNo
- "auto" (default) which maps to UITextSpellCheckingTypeDefault
For consistency, I decided to use the same API design as spellCheck. We don't have many options for fixing spellCheck in #11055 without introducing a breaking change.
**Test plan (required)**
Verified that switching `spellCheck` between `true`, `false`, and `null` all work correctly in single line and multiline `TextInputs`.

Summary:
To make React Native play nicely with our internal build infrastructure we need to properly namespace all of our header includes.
Where previously you could do `#import "RCTBridge.h"`, you must now write this as `#import <React/RCTBridge.h>`. If your xcode project still has a custom header include path, both variants will likely continue to work, but for new projects, we're defaulting the header include path to `$(BUILT_PRODUCTS_DIR)/usr/local/include`, where the React and CSSLayout targets will copy a subset of headers too. To make Xcode copy headers phase work properly, you may need to add React as an explicit dependency to your app's scheme and disable "parallelize build".

Summary:
There's an inconsistency in autoCorrect's default state:
- If you don't specify a value for autoCorrect, it defaults to on.
- If you specify true/false for autoCorrect and later specify null, autoCorrect turns off. It should have reverted to its initial state of on.
The reason for this discrepancy is that autoCorrect is exposed to JS as a boolean but it is actually an enum with three states in native:
- UITextAutocorrectionTypeDefault (the default value)
- UITextAutocorrectionTypeYes
- UITextAutocorrectionTypeNo
This is fixed by explicitly mapping JS null to UITextAutocorrectionTypeDefault.
**Test plan (required)**
Verified that switching `autoCorrect` between `true`, `false`, and `null` all work correctly in single line and multiline `TextInputs`.

Summary:
We had a classic integer underflow problem here. Before we would let you type endlessly when the text already exceeded the TextInput maxLength, now we only let you erase characters.
There is still a small problem with the TextInput: how do you handle when the value (set from JS) exceeds the maxLength? This could happen pragmatically, just by passing in a very large value or when changing maxLength (e.g. when changing from 4 to 3 digits in the case of a AMEX security code -> VISA security code).
Me and achen1 discussed firing onChange in these cases and truncating the number manually (to ensure JS's data model) was aware of the change but it seemed fraught with bugs and general weirdness in what the caller would expect to happen.

Summary:
This adds support for a controlled `selection` prop on `TextInput` on iOS (Android PR coming soon). This is based on the work by ehd in #2668 which hasn't been updated for a while, kept the original commit and worked on fixing what was missing based on the feedback in the original PR.
What I changed is:
- Make the prop properly controlled by JS
- Add a RCTTextSelection class to map the JS object into and the corresponding RCTConvert category
- Make sure the selection change event is properly triggered when the input is focused
- Cleanup setSelection
- Changed TextInput to use function refs to appease the linter
** Test plan **
Tested using the TextInput selection example in UIExplorer on iOS.
Also tested that it doesn't break Android.

Summary:
This introduces event counts to make sure JS doesn't set out of date values on
native text inputs, which can cause dropped characters and can mess with
autocomplete, and obviates the need for the input buffering which added lag and
complexity to the component. Made sure to test simulated super-slow JS text
event processing to make sure characters aren't dropped, as well as typing
obviously correctable words and making sure autocomplete works as expected.
TextInput is now a controlled input by default without causing any issues for
most cases, so I removed the `controlled` prop.
Fixes selection state jumping by restoring it after setting new text values, so
highlighting the middle of some text in the new ReWrite example and hitting
space will replace that selection with an underscore and keep the cursor at a
sensible position as expected, instead of jumping to the end.
Ads `maxLength` prop to support the most commonly needed syncronous behavior:
preventing the user from typing too many characters. It can also be used to
prevent users from continuing to type after entering special characters by
changing it to the current length after a regex match. Made sure to verify it
works well with pasted input (including in the middle of existing text),
truncating it and collapsing the selection the same way it does on the web.
Fixes bug in TextEventsExample where it wouldn't show the submit and end events,
even though there were firing correctly.
