Android: remove ContentViewCore from the renderer crash codepath.

This patch employs base::TerminationStatus to communicate the state of the oom
bindings when a child process dies and exposes renderProcessGone() in
WebContentsObserverAndroid, removing the need for ContentViewCore to be
involved in the renderer crash codepath.

This allows to drop tracking the pid of the renderer process in ContentViewCore
and eliminates the need for the |tab_crashed_| flag in native
ContentViewCoreImpl.

Move the OverlayShowDoesntShift test to a lighter-weight test case

OverlayDShowDoesntShift doesn't use any of the extended functionality of
OptionsWebUIExtendedTest, so move it into the simpler OptionsWebUITest.
This is a speculative change to fix the occasional flakiness of this test --
but it's also valid cleanup in its own right.

sync: treat gaia http 500s as retriable.

Both OAuth2TokenService and ProfileSyncService will now retry on HTTP 500s. Note that ProfileSyncService retries will only kick in if OA2TS gives up after a fixed number of attempts.
