* Added some thread asserts to the code and made ios_surface_ safe since
its being written and read from different threads.
* responded to chinmays feedback, added comment
This keeps us from setting the text on a node if it is a SCOPES_ROUTE node, and sends the "TYPE_VIEW_FOCUSED" event when we update the semantics information and a view has the input focus.
* [flutter_runner] Make rd and rx uniform
Currently we pass paths for readonly files and pass
in fds for rx. Now passing in fds everywhere.
* pass full paths
This reverts commit c2879cae2ee3707ad07af1118bf4862dc1d82bb7.
Additionally, we fix https://github.com/flutter/flutter/issues/40863 by adding a secondary VSYNC callback.
Unit tests are updated to provide VSYNC mocking and check the fix of https://github.com/flutter/flutter/issues/40863.
The root cause of having https://github.com/flutter/flutter/issues/40863 is the false assumption that each input event must trigger a new frame. That was true in the framework PR https://github.com/flutter/flutter/pull/36616 because the input events there are all scrolling move events. When the PR was ported to the engine, we can no longer distinguish different types of events, and tap events may no longer trigger a new frame.
Therefore, this PR directly hooks into the `VsyncWaiter` and uses its (newly added) secondary callback to dispatch the pending input event.
This adds an isFocusable to SemanticsFlag so that the framework can tell the engine what semantics nodes are allowed to be focused, which will affect what platform flags are applied to the semantics information.
This flag is not yet in use by the frame
This reverts commit fcc4ab32301396986dd5103d6d444bff35fe0f63.
Fixes https://github.com/flutter/flutter/issues/41394 and other
related correctness issues.

Started asserting the FlutterEngine is running before communicating
over channels. This changes a null pointer exception to an
NSException that will provide some meaningful data to clients
incorrectly using the engine in an add-to-app situations.
- Don't use 'unhandled' as that implies fatality which this is not
- Don't mention shutdown because this is not necessarily an exception-after-shutdown issue
Follow-up issue filed https://github.com/flutter/flutter/issues/41506 to implement the unit test for this.
Made creating and using a FlutterEngine a bit easier, to try to get it get it as easy to use as Android's equivalent.
* Added a default entrypoint variable.
* I added `run` to and `initWithName:` to FlutterEngine.
This change modifies the accessibility bridge so that if a node has input focus, then it will tell TalkBack so that it will request the accessibility focus for the view.
It also sets the content change types bit field to include CONTENT_CHANGE_TYPE_SUBTREE to indicate that the subtree for the view has changed for API levels after, and including, KitKat (19)
Samsung's Korean keyboard has a bug where it always attempts to combine
characters based on its internal state, ignoring if and when the cursor
is moved programmatically. EG typing "ㄴㅇ" and then moving the cursor
back to the front of the text and typing "ㄴ" again would result in
"ㄴㅇㄴ", not "ㄴㄴㅇ".
Fully restarting the IMM works around this because it flushes the
keyboard's internal state and stops it from trying to incorrectly
combine characters. However this also has some negative performance
implications, so we only apply the workaround on Samsung devices set
to use Korean input.
This also effectively disables the feature on Samsung keyboards that
allowed users to re-open a composing region for previously typed
characters. See https://github.com/flutter/flutter/issues/29341#issuecomment-531283508.

On Fuchsia, add a build flag for compositing OpacityLayers using the system
compositor vs Skia, which exposes a fastpath for opacity via Scenic.
This will only work under certain circumstances, in particular nested
OpacityLayers will not render correctly!
On Fuchsia, add a build flag for compositing PhysicalShapeLayers using
the system compositor vs Skia. Set to off by default, which restores
performant shadows on Fuchsia.
Remove the opacity exposed from ChildView, as that was added mistakenly.
Finally, we centralize the logic for switching between the
system-composited and in-process-composited paths inside of
ContainerLayer. We also centralize the logic for computing elevation
there. This allows the removal of many OS_FUCHSIA-specific code-paths.
Test: Ran workstation on Fuchsia; benchmarked before and after

This changes writes the required and current Android SDK level to the exception message. This enables Crash Reporting tools to capture more information about this crash.
