Steven Novaryo 45c39d7496 script: Notify PinchZoom resizes to ScriptThread's VisualViewport (#41754) ...

Continuing the implementation of `VisualViewport`, the resizing of
`PinchZoom` should be notified to `ScriptThread` to update the
`VisualViewport` interface and to fire the appropriate JS event. Top
level `Window`/`Pipeline` would have a `VisualViewport` interface that
mirrors the `PinchZoom` viewport, while nested `Window` would have a
default value that represent layout viewport of the relevant iframe. The
`VisualViewport` of an iframe is updated after each reflow that
calculate the rectangle of the iframe.

The updates of DOM's `VisualViewport` occurs immediately (instead of
waiting for the event loop like the viewport) but integrates with the
event loop for the JS events. This behavior would helps with the fact
that `VisualViewport` needs to be updated both when it is scrolled or
resized.

Testing: Existing WPTs and new unit test.
