script: Get the screen metrics from the WebViewDelegate instead of via the compositor (#38020)

Browse source 
Similar to #37960, previously, `AvailHeight`, `AvailWidth`, `Height`,
`Width` ask compositor for screen metrics. This PR moves the request to
embedder.

This simplifies code, and reduces workload of compositor, which is
busier most of time.

Testing: No behaviour change. Updated some tests. `Width/Height` matches
other browsers.
