Android overrides the original set ime option when the EditText is a multiline one.
This change makes sure to set it back to the original one when blurOnSubmit is true,
which causes the button icon to be conforming to the set returnKeyType as well as
changing the behaviour of the button, such that it will blurOnSubmit correctly.
The reason not do it with blurOnSubmit being false is
because it then would not create new lines when pressing the submit button,
which would be inconsistent with IOS behaviour.
**Note** this change relies on this one #11006 because the app would crash if we don't expllicitly remove the focus (`editText.clearFocus();`)
Fixes#8778
**Test plan (required)**
1. Create view with TextInput with multiline and blurOnSubmit set to true
```javascript
<View>
<TextInput
returnKeyType='search'
blurOnSubmit={true}
multiline={true}
onSubmitEditing={event => console.log('submit search')}></TextInput>
</View>
```
2. Input some text and click submit button in soft keyboard
3. See submit event fired and focus cleared / keyboard removed

Summary:
Fixes#12591
The Android JSTouchDispatcher was using `mTargetCoordinates` when creating the TouchEvent for a move. However, these are final values which are set when the touch down is received. When the user's finger moves, it's important to be able to track the coordinates of the touch as it moves. Thus, we need to update the x,y coordinates by calling `TouchTargetHelper` on each move event.

I was trying to typeset mathematical equations in react native. When typesetting fractions, baseline of the fraction must be aligned with the baseline of others. The baseline of fraction will vary based on size of numerator and denominator.
In yoga, we can set custom baseline function using `YogaNode.setBaselineFunction` method. If this method is exposed in `ReactShadowNode` class, it will be easy to create custom native UI modules which requires setting custom baseline.

Summary:
Currently, `onLoadStart` fires for a couple of cases:
1. toplevel page loads (e.g. initial page load, clicking links)
2. loading of pages within an iframe
The fact that `onLoadStart` fires for case (2) causes some problems. For example, it makes it difficult for the code that uses the WebView to know what URL the WebView is currently rendering. This is because the listener can't distinguish between the toplevel URL and the URL of an iframe. Additionally, this behavior is inconsistent with the behavior on iOS. On iOS, `onLoadStart` only fires for toplevel page loads.
To fix these issues, this change deletes the `doUpdateVisitedHistory` handler so that `onLoadStart` only fires for case (1).
**Test Plan**
Created a test page that has an iframe and loaded it in the WebView. Verified that `onLoadStart` only fires for toplevel page loads.

Summary:
Overview -
This PR resolves the issue described in #14606. This PR makes Text components take into account the includeFontPadding property when calculating their size.
Background -
Currently, on Android, when includeFontPadding is set to false, the React Text component does not adjust its height. This makes it difficult to lay out other components at a precise spacing relative to a Text component.
iOS calculates the height of a UILabel based on the font's descent + ascent.
Android lets you choose whether to calculate the height of a TextView based on the font's top + bottom (includeFontPadding=true) or ascent + descent (includeFontPadding=false).
In order for a text component to be the same size on iOS and Android (relative to the rest of the layout in points and dips), one should set includeFontPadding=false on Android - but the React Text component needs to take this property into account when sizing itself for this to work.
Please see this stack overflow post for a visual explanation of the difference between a font's ascent/descent and top/bottom - https://stackoverflow.com/questions/27631736/meaning-of-top-ascent-baseline-descent-bottom-and-leading-in-androids-font
Testing -
Please see the attached screenshots to see the height difference of a Text component with this PR when includeFontPadding is true vs false.
The font I am using has an ascent + descent = em-size so that the height of the Text component will be equal to the font-size for a single line of text. This is to clearly show the additional height that includeFontPadding=true adds to the Text component.
For Text components that are styled in the same way,
When includeFontPadding=true, height = ~29.714 dips
When includeFontPadding=false, height= 24 dips

Summary:
This is a workaround for missing PDF url support in Android WebView, which is a general known issue: when tapping a PDF url within WebView, instead of doing nothing, we just let android default intent handle it (e.g. it will open Chrome to load it).
This is basically to trick `shouldOverrideUrlLoading()` to return true for the specific url. The drawback is that product code needs to provide the whitelist.
The proper fix would be to use PdfRenderer in that method, but it seems like it's only for API >= 21...

Summary:
Since the `hot` parameter is not used anymore in metro-bundler (we are always applying the HMR transforms for bundlers requested through the HTTP server), we can remove it from the client request URL.
This allows us to reduce the metro-bundler memory by half when switching between HMR and not-HMR, since metro caches the bundles based on the requested URL path.

Summary:
We ran into a couple of problems with the implementation of `getCurrentPosition` on Android:
- It sometimes returns an inaccurate location
- It times out when `enableHighAccuracy` is `true` (#7495)
This change improves `getCurrentPosition` for both of the above problems. Instead of calling `requestSingleUpdate` it now calls `requestLocationUpdates` so it can receive multiple locations giving it an opportunity to pick a better one. Unlike `requestSingleUpdate`, this approach doesn't seem to timeout when `enableHighAccuracy` is `true`.
**Test plan (required)**
Verified in a test app that `getCurrentPosition` returns a good location and doesn't timeout when `enableHighAccuracy` is `true`. Also, my team has been using this change in our app in production.
