This (mostly) re-lands #21163, which was reverted in #22321
This switches from using onKeyDown to using dispatchKeyEvent on Android so that keys can be intercepted handled by the framework and not continue to be dispatched to other controls.
It also now intercepts key events sent to InputConnection.sendKeyEvent, as some IMEs do (e.g. the Hacker's Keyboard), and sends them to Flutter.
This fixes the problem where (for example) pressing TAB on a hardware keyboard sends the tab to both the text field and to the focus traversal system.
Note that we still can't intercept all keystrokes given to a soft keyboard, only those which the soft keyboard decides to send to InputConnection.sendKeyEvent, and system keys (like the back button) are only received if the IME doesn't eat them.
This re-lands #21163, which was reverted in #22004
Now that flutter/flutter#67359 has landed, this change will no longer cause spaces (and other shortcuts) to be ignored in text fields if there is no action associated with the intent, even if there is a shortcut key mapping to an intent.
It also no longer causes web test failures (as far as I can tell without submitting it: the same tests don't fail locally).
Here's the original PR description:
This switches from using dispatchKeyEvent to using dispatchKeyEventPreIme so that keys can be intercepted before they reach the IME and be handled by the framework.

WindowInsetsAnimation.Callback was introduced in API level 30. This
PR moves the text input plugin's WindowInsetsAnimation.Callback subclass
into a class that will only be loaded if the embedding has checked for a
sufficient API level.

If the InputConnectionAdaptor receives a key event that does not move
the caret or produce a text character (such as the back button), then
the event should be given to the EventResponder which will forward it
to the view.

This re-lands the key event synthesis implementation for Android (Original PR: #19024, Revert PR: #19956). The only difference is sending the synthesized key events to the root view instead of the current view.
Without sending it to the root view, the system doesn't have any chance of handling keys like the back button. The event will still not be sent to the framework twice, since we turn off event propagation while re-dispatching the event.
AccessibilityBridge installs various listeners for Android events
that invoke Flutter engine APIs. These listeners are removed in
AccessibilityBridge.release. However, in some environments there may
be deferred calls to the listener that will still execute even after
the listener has been removed. This change sets a flag during release
and ignores any listener invocations that happen after the flag is set.
