This reverts commit a5e0b2f2.

Fixes https://github.com/flutter/flutter/issues/54275

The BaseInputConnection superclass does not call endBatchEdit
in setSelection and therefore does not implicitly cause
InputConnectionAdaptor to send a state update.

Some input modes such as numeric keypads will not function without
these updates.

* Revert getSystemGestureExclusionRects and setSystemGestureExclusionRects 

* Remove references to removed PlatformChannelTest.java file

* Android change to match the google internal changes.

* Fix format.

* Revert format change, add super call.

* Remove comment for API version.

Fixed splash screen crash when bringing Android app back to foreground after being evicted from memory. (#47635) (#16916)

* Add support for software text editing controls

Includes selection, copy, cut, paste, as well as partial support for up
and down movement.

Text editing controls can be accessed in GBoard by:
  top-left arrow > three dots menu > text editing

Partial fix for flutter/flutter#9419 and flutter/flutter#37371.

* Introduce InputConnectionAdaptor tests

Run with:
  testing/run_tests.py --type=java --java-filter=io.flutter.plugin.editing.InputConnectionAdaptorTest

* Fix BUILD.gn comment on run_tests.py --java-filter flag

Exposes FlutterSurfaceView, and FlutterTextureView to FlutterActivity and FlutterFragment. (#41984, #47557) (#16552)

The formatter didn't understand what was going on here and broke the
text. Changed these to use `<pre>{@code }</pre>` instead.
