Plumb cc hit test regions to viz.
This CL adds a HitTestDataProvider class for cc layer trees. It generates hit
test data based on surface layers and property trees in cc. The data will be
submitted to viz during SubmitCompositorFrame and be used by HitTestQuery.
This change is hidden behind a flag --use-viz-hit-test-surface-layer. It is
the first of a series of changes. This CL is expected to be functionally
equivalent to generating HTRLs from CompositorFrame draw quads, but it allows
additional data being plumbed in the future CL.
