Track per-window information in ViewFrameInfo

FrameInfo will now be per-window; that is, per-ViewRootImpl.
Some of the information should remain “global” (it remain in Choreographer),
while some information is going to become ViewRootImpl-specific.
Before the information gets passed to the native layer,
 the ViewRootImpl-specific info will be stitched together
with the general Choreographer info.

This change is useful in order to correctly correlate frames with a specific
input event. In the unlikely scenario of a user touching two windows of the
same app simultaneously, this change will allow us to correctly measure the
latency of both frames produced by the windows.
