commit 8ca10fb2914087fd1b2589dedf69f615595bdb4c
Author: btolsch <btolsch@chromium.org>

Refactor 2-UA messaging

This change allows MRPs to supply a pair of
blink::mojom::PresentationConnection mojo pipes to be used to directly
communicate with the controller in place of
BrowserPresentationConnectionProxy.  The mojo pipes are optional, to
allow backwards compatibility with extension versions that don't yet
support this change.  PSDImpl will revert to using
BrowserPresentationConnectionProxy if no pipes are provided in an
otherwise successful route reponse.
