This is the first step in making Flutter aware of and responsive to Z
bound overflow. On its own this patch shouldn't result in any changes in
behavior. This will need to be followed up with a patch in Fuchsia's
Flutter runner to set the Z bounds after this lands, and another patch
in the engine actually implementing the desired overflow behavior.
This Z bound info is routed through the engine itself to make sure the
bounds in flow are truly consistent from the Fuchsia runner. However
these values should eventually be exposed to the framework as well.
Some components in the Flutter engine were derived from the forked blink codebase. While the forked components have either been removed or rewritten, the use of the blink namespace has mostly (and inconsistently) remained. This renames the blink namesapce to flutter for consistency. There are no functional changes in this patch.
The font manager returned by SkFontMgr::RefDefault is determined by Skia's
build configuration flags. Embedders may want to use a default font manager
other than the one selected by their build of Skia.
The DartPersistentValue used to hold the image callback is tied to a
Dart isolate. Destructing the DartPersistentValue requires entering
the isolate and must be done on the UI thread.

Follow up the framework change in flutter/flutter#29304.
Inject the accessibility element tree in the semantic node if the node is for platform views.

We used to make tonic make the wrapper before the SendPlatformMessage invocation. However, tonic would not collect the wrapper before make the Dart API call to return the value from the native method. This is illegal and would trip an assertion in the Dart VM. A more systematic fix required reworking tonic to handle this case. However, to fix our illegal use of the Dart API now, this patch creates the wrapper manually in function scope.

Adds support for pointer signals, in a way that will support both discrete events (e.g., scroll wheels, flutter/flutter#22762) and continuous gestures (e.g., trackpad scroll, flutter/flutter#21953).
Also exposes these new event options to the embedder. Does not include code to send the
new events from the platform shells.
This brings the Dart and C++ semantics flag enums back in sync.
In #5902, the ability to move the cursor forward and backward one word
were added to dart:ui, and to the Android embedder, but not to the
SemanticsAction enum on the C++ side.
This brings the Dart and C++ semantics flag enums back in sync.
In #5941, implicit scrolling support was added to SemanticsFlag in
dart:ui, and to the Android embedder, but not to the SemanticsFlags enum
on the C++ side.
This also clarifies/corrects the documentation for this value in dart:ui
and in the embedder API.
