* fixes voice over for higher ios-safari versions
* change enable conditions for webkit
* adding click event for removal. adding unit tests
* run the mobile semantics enabler test on mobile browsers
* remove test method that gave different result on LUCI.(further inv. needed)
* enable safari tests for almost all the methods for semantics tests
* enable almost all semantics tests for firefox
* Safari desktop have different scroll max values for different versions
* fix assert
This re-lands #20496 and #21780 after fixing the semantics-enabling code that was causing the post-submit web_smoke_test to fail.
Below is the description from the original PR:
This is a PR for converting the dart:ui code in the engine to use a multi-window API. The goal here is to convert from the window singleton to an API that has the concept of multiple windows. Also, I'm matching up the new PlatformDispatcher class to talk directly to the PlatformConfiguration class in the engine. I'm not attempting to actually enable creating multiple windows here, just migrate to an API that has a concept of multiple windows. The multi-window API in this PR currently only ever creates one window.
The design doc for this change is here.
The major changes in this PR:
Move the platfom-specific attributes out of Window, and into the new PlatformDispatcher class that holds all of the platform state, so that the platform code need only update the configuration on this class.
Create FlutterView, FlutterWindow, and SingletonFlutterWindow classes to separate out the concepts of a view (of which there may be multiple in a window), a window (of which there may be multiple on a screen, and they host views), and a window where there is only ever expected to be one (this hosts the entire API of the former Window class, and will eventually be the type of the window singleton).
Next step after this PR lands:
Remove the Window class entirely (it is replaced by SingletonFlutterWindow). Some minor changes in the Framework are needed to switch to using SingletonFlutterWindow directly first.
The Window class still exists in this PR, but will be removed as soon as the framework is converted to point to the SingletonFlutterWindow class instead. They share the same API, just have different names (Window is currently a subclass of SingletonFlutterWindow). The intention is that the Window name will be freed up to use as a widget class name in the framework for managing windows. The singleton called window will remain, and keep the same API it has now.

This change converts all Float64List matrices to Float32List at the dart:ui interface boundary. Internally, it only uses Float32List. Float32List requires less memory and is orders of magnitude faster to allocate, and it has sufficient precision as Flutter mobile engine and Skia use 32-bit floats anyway.
This change speeds up frame preroll by 50% on the bench_card_infinite_scroll benchmark.
For more details on Float64Array allocation in JS (which backs Float64List in Dart) see the following:
