Subject : Move synthetic gesture input to be aligned with BeginFrame.
Author  : dtapuska
Commit description:
  
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.

Reland https://codereview.chromium.org/2372873003. It was reverted because
of a regression that was fixed in https://codereview.chromium.org/2385333002
