[VirtualKeyboard] Android VK API implementation Part 2.

This patch contains the geometrychange JS event and overlayscontent
implementation of the new VirtualKeyboard APIs on Android.
This is a new feature that would let web authors to control whether
they want the default occlusion of web content and changing of visual
/layout viewport in response to VK visibility or not. The explainer
has some examples as to where this would be useful and how it would
be used by the web authors.
