necessary to maintain behavior and adds some small modifications
to handle the change in nullability. Warnings about unnecessary
null assertions are disabled temporarily in this CL as well.

Moving the caret with the software Dpad now correctly considers complex characters.

Changed iOS channels to start cleaning up the accessibility handler when the bridge is deleted (#19556)

Started cleaning up the accessibility handler when the bridge is
deleted and made nilling out channels safer by making sure they don't
overwrite newly setup handlers.

Translate the coordinate from global flutterview to the specific embedded sub-view.

UIKit does not guarantee that the application is in the active state when it
lays out it subviews. However, in `viewDidLayoutSubviews`, Flutter attempts to
create the render surface and wait for the first frame. These operations require
GPU access which is forbidden when in the background on iOS. This layout while
in the background only seems to happen under very specific circumstances as
described in the reproducible test case. Notably, this behavior cannot be
reproduced when the application is just launched with the "Background Fetch"
XCode run scheme. The other instance of invocations to create the rendering
surface have been audited and I can confirm that those are already in the
correct lifecycle callbacks. This was the only instance where the surface
creation was in a non-lifecycle callback.

Fixes https://github.com/flutter/flutter/issues/55969
(This issue has a clear reproducible test case and was used as the basis for
verification.)
Fixes https://github.com/flutter/flutter/issues/57676
(This is significantly harder to reproduce but the issue looks to be the same. I
tried this patch on multiple devices overnight and could not reproduce this.)

This underlying cause here was identified by the enhanced GPU error reporting
introduced in iOS 14. I am not able to submit those patches because the Beta
builders are not available on infra. I will submit those when available so that
issues like this have more actionable error messages in the future.
