servo: Track async webview focus operations (#38243)

Browse source 
https://github.com/servo/servo/pull/38160 added a webdriver-specific API
to support waiting on focus operations to complete. These changes
replace that with a generalized pattern, where a unique ID is created
for each focus operation and the embedder can receive notifications
about each focus operation when it is complete, regardless of whether
the focus was actually changed.

Testing: Existing test coverage from
https://github.com/servo/servo/pull/38160/ is unchanged.
