Reduce duplicated code in AwWebContentsDelegate

Reduce duplicated code in AwWebContentsDelegate

This is pure refactoring. Functionality should not be affected.
CL reduces duplicated code that AwWebContentsDelegate copied
from WebContentsDelegateAndroid.

Background: This cleanup is a first step towards moving the
responsibility of ContentVideoView from the content embedders to
the content-layer. The goal is to let WebContentsDelegateAndroid's
ExitFullscreenModeForTab do the work that is common to both
WebViews and Android Chrome; for example, tearing down
ContentVideoView when fullscreen exits.

aren't you misssing the call to

web_contents->GetRenderViewHost()->WasResized();

here?
