Summary:
**Motivation**
Whenever a user changes the system font size to its maximum allowable setting, React Native apps that allow font scaling can become unusable because the text gets too big. Experimenting with a native app like iMessage on iOS, the font size used for non-body text (e.g. header, navigational elements) is capped while the body text (e.g. text in the message bubbles) is allowed to grow.
This PR introduces a new prop on `<Text>` and `<TextInput>` called `maxFontSizeMultiplier`. This enables devs to set the maximum allowed text scale factor on a Text/TextInput. The default is 0 which means no limit.
Another PR will add this feature to Android.
**Test Plan**
I created a test app which utilizes all categories of values of `maxFontSizeMultiplier`:
- `undefined`: inherit from parent
- `0`: no limit
- `1`, `1.2`: fixed limits
I tried this with `Text`, `TextInput` with `value`, and `TextInput` with children. For `Text`, I also verified that nesting works properly (if a child `Text` doesn't specify `maxFontSizeMultiplier`, it inherits it from its parent).
Lastly, we've been using a version of this in Skype for several months.
**Release Notes**
[GENERAL] [ENHANCEMENT] [Text/TextInput] - Added maxFontSizeMultiplier prop to prevent some text from getting unusably large as user increases OS's font scale setting (iOS)

Summary: This adds a callback for <Text> to get metrics about the rendered text. It's divided by line but that could be changed to "fragments" (which makes more sense for multi-lingual). Right now by line is convenient as you frequently want to know where the first and last line end (though we could make this work with fragments I suppose).

Summary:
This PR removes the need for having the `providesModule` tags in all the modules in the repository.
It configures Flow, Jest and Metro to get the module names from the filenames (`Libraries/Animated/src/nodes/AnimatedInterpolation.js` => `AnimatedInterpolation`)
* Checked the Flow configuration by running flow on the project root (no errors):
```
yarn flow
```
* Checked the Jest configuration by running the tests with a clean cache:
```
yarn jest --clearCache && yarn test
```
* Checked the Metro configuration by starting the server with a clean cache and requesting some bundles:
```
yarn run start --reset-cache
curl 'localhost:8081/IntegrationTests/AccessibilityManagerTest.bundle?platform=android'
curl 'localhost:8081/Libraries/Alert/Alert.bundle?platform=ios'

Summary:
Previously, the Platform module was used to detect when RCTVirtualText should be used. Recently, this has changed to detecting the availability of a native virtual text component on the UIManager. The import for the Platform module can be deleted.
I was cleaning up source code copied in react-native-windows and noticed this reference is no longer used in Text.js.
Run jest tests.

Summary:
Currently `isInAParentText` context works as imaginary `isInAAncestorText` context (not like a real `isInAParentText`).
Let's imagine we have hierarchy like:
`View -> Text -> Text* -> View* -> Text* -> Text* -> View*`
With current implementation all nodes marked with asterisk have `isInAParentText` context, which is incorrect (because some of them actually in View context).
With the new implemetations it will work like this:
`View -> Text -> Text* -> View* -> Text -> Text* -> View*`
So, only nodes which have <Text> (or <TextInput>) as a parent will have `isInAParentText` context.
This change allows to select proper `Text` vs. `VirtualText` component in cases where <Text> and <View> components can interleave each other.

Summary:
The relevant changes in the PR are to Libraries/StyleSheet/EdgeInsetsPropType.js; the rest are just removals of FlowIgnores.
The definition of the relevant types is [here](https://github.com/facebook/flow/blob/master/lib/react.js#L262-L271).
The long and short of it is that for whatever reason, Flow is unable to realize that `ReactPropsChainableTypeChecker` is a subtype of `ReactPropsCheckType` unless we assert it. Once we explicitly hint this to the typechecker, it realizes that `EdgeInsetsPropType` is indeed a valid React PropType, and stops complaining that it isn't.

Summary:
Android has a text API called breakStrategy for controlling how paragraphs are broken up into lines. For example, some modes support automatically hyphenating words so a word can be split across lines while others do not.
One source of complexity is that Android provides different defaults for `breakStrategy` for `TextView` vs `EditText`. `TextView`'s default is `BREAK_STRATEGY_HIGH_QUALITY` while `EditText`'s default is `BREAK_STRATEGY_SIMPLE`.
In addition to exposing `textBreakStrategy`, this change also fixes a couple of rendering glitches with `Text` and `TextInput`. `TextView` and `EditText` have different default values for `breakStrategy` and `hyphenationFrequency` than `StaticLayout`. Consequently, we were using different parameters for measuring and rendering. Whenever measuring and rendering parameters are inconsistent, it can result in visual glitches such as the text taking up too much space or being clipped.
This change fixes these inconsistencies by setting `breakStrategy` and `hyphenat
