Move synthetic gesture input to be aligned with BeginFrame.

Move synthetic gesture input to be aligned with BeginFrame.

The timing of synthetic events seems almost random. It is best to align
it with something that doesn't fluctuate. Android already rAF aligns its
synthetic input so do this for aura and mac as well.

A revert of this CL (patchset #2 id:20001) has been created in
https://codereview.chromium.org/2390813002/ by dtapuska@chromium.org.

The reason for reverting is: Appears RenderWidgetHostViewChildFrame ends up
calling a virtual during the constructor and this isn't getting called. This is
an existing bug.

But the change in this CL reveals this bug so reverting this change for now.
