Window.viewInsets is the set of window-relative insets that describe the
area of the window that an application may want to treat as effectively
reducing the size of the content. Typically this is due to system UI
that fully obscures underlying content, such as the keyboard.
This area differs from padding in that padding is the set of insets that
describe the area of the window that may be partially (or fully)
obscured by system UI or physical intrusions into the view area (e.g.
iPhone X sensor housing, status bar, or the iPhone X home indicator
widget).
This patch does not yet enable the iOS bottom edge safe area. Once the
framework has been updated to use viewInsets for bottom-edge occlusions
(today, the keyboard), the bottom safe area will be enabled and
framework patches that depend on it, landed.
- Assumes only the Dart VM is interested in idle notification.
- Gives the VM the time remaining in each frame.
- Gives the VM 100ms if there is no pending frame.
Issue flutter/flutter#9594
* Add back launch screen view until first frame on iOS
* improvements
* Move callback plumbing from ios surfaces to the gpu rasterizer. Didn’t wire java JNI yet.
* Android JNI
* Fix ios reference count and let android engine manage a view on top with launch screen
* Hook up Android activity and view
* review notes
* review notes
* Move thread switching upstream. Use weak references for callbacks.
* Some clean up
In particular, this avoids some unnecessary calls to InputMethodManager.restartInput
that caused noticeable lag when moving the cursor.

This factors the functionality that was in `FlutterActivity`
to live in `FlutterActivityDelegate`. This will allow the creation of a
`FlutterFragmentActivity` that has the same core functionality, which in
turn unlocks certain Android plugins that choose to require the v4
support library (like Google Sign-In).

**This is a breaking change on iOS**
Previously, the `paused` state was entered when the application resigned
active status. `inactive` now maps to this status. `paused` now maps to
an app that has been backgrounded.
`inactive` is currently emitted on iOS only and corresponds to iOS's
foreground inactive state.
Current state transitions are:
`resumed` <--> `inactive` <--> `paused`
suspending is currently emitted on Android only and corresponds to the
transition to Android's stopped state.
Current state transitions are:
`resumed` <--> `paused` --> `suspending` --> `resumed`
These transitions may change in future.
The core problem was multiplying matrices the wrong way around.
While I was there I did some minor cleanup. I think that may have
fixed another bug relating to A11Y turning on or off improperly, but
since I never figured out the steps to reproduce, it's hard to tell.

Fixes https://github.com/flutter/flutter/issues/10059 (maybe)
Breaking change: removed facilities for JSON and string messaging from FlutterView/FlutterViewController, leaving only binary messaging there. All other use of flutter communication now goes through FlutterMessageChannel and FlutterMethodChannels. Retained use of String and JSON codecs for now.
Companion flutter PR: flutter/flutter#8837
FlutterView's host message processing methods are invoked from native code,
and the JNI wrappers will abort the process if the Java side has an uncaught
exception.
