commit 60af7d4ec5c53c88494e6d87a83434732031dce7
Author: Becca Hughes <beccahughes@chromium.org>

Autoplay: Replicate user gesture before nav bit.

The "HasUserReceivedUserGestureBeforeNavigation" bit is currently
local to Blink and activation delegation will require that we can
access this bit across cross origin iframes. This means we need
to replicate this across processes.

The tests include coverage for feature policy to ensure it works
correctly with the delegation.
