to the value returned by KeyEvent.getRepeatCount() and add it to the
message passed through the channel with the intention of exposing it
in RawKeyEventDataAndroid on the framework side.

* Use the actual devicePixelRatio in the Skia backend

* Get the coordinates of mouse events in physical pixels

* disable canvaskit by default

This re-enables thread safety checks for WeakPtr. WeakPtrs can't be used on a thread other than the one the WeakPtrFactory was created on.

This fixes the unit tests and adds a getUnsafe() method to WeakPtr to work around the remaining unresolved locations where we are using WeakPtr unsafely.

This reverts commit 6c2381da and applies iOS fixes.
