capture_mode: Add support for window capture

Implement the proposal presented in the design doc
http://go/window-capturing to make the
FrameSinkVideoCapturer able to record non-root windows.

tl;dr The idea is to tag the layer of the non-root window
with a unique ID (of type viz::SubtreeCaptureId) that will
result in forcing this sub layer tree into a render surface
that draw into a render pass identifiable by that ID to the
FrameSinkVideoCapturerImpl on the viz side.

BUG=1143930
TEST=- Manually.
     - Added new tests:
        - (viz_unittests) CompositorFrameSinkSupportTest.CopyRequestOnSubtree
        - (aura_unittests) WindowTest.*Capturable*
        - (ash_unittetss) CaptureModeTest.WindowRecordingCaptureId
        - (browser_tests) RecordingServiceBrowserTest.RecordWindow
        - (cc_unittests) *LayerTreeHostCaptureTest*
     - Modified many tests else where.
