[WebView Support Lib] Mix frameworks and support lib impls together.

This CL re-implements ServiceWorkerControllerCompat and
ServiceWorkerWebSettingsCompat in a fashion allowing us to choose on a
per-method basis whether to use framework APIs or the support library
glue.
This makes feature detection more consistent for post-L classes with new
methods added after P.

Bug: 77808798
Test: run androidx.webkit tests.
