[Cronet] Add new API methods before removing old ones

To allow embedders to update to the new API piecemeal, rather than
forcing an all-at-once update:
1. Allow mocking of UrlRequest.Builder by making non-final. This
   allows embedders to prepare for removal of CronetEngine.createRequest().
2. Add CronetEngine.newUrlRequestBuilder()

Andrei, PTAL, thank you!  I imagine we could get this merged to M55 easily.
