[Android WebView] Add a first version of the support library glue layer

WebView already has a webkit <-> chromium glue layer.
This CL introduces a WebView-support-library <-> chromium glue layer to
allow the WebView Support Library to use reflection to access WebView
functionality without being restricted by the android.webkit framework
APIs.

In terms of layering the idea here is to have the support library glue
depend on 'shared' classes in the webkit-glue layer (ideally those
classes would be broken out into their own layer but for now they
contain too many dependencies on the webkit-glue layer).

With this CL we add support for the single API
WebViewCompat.postVisualStateCallback().

Include support library glue into monochrome and system_webview_apk

The WebView Support Library glue layer is the chromium-side part of the
WebView Support Library - the rest lives in the Android Support Library.

Since the WebView Support Library glue layer does not depend on
anything downstream we can include it in all upstream WebView targets.
