Use blast sync for changing screen resolution

Windows with PRIVATE_FLAG_IS_ROUNDED_CORNERS_OVERLAY will be put
on top layer and by default it is excluded from screenshot.
So before the animation starts, their drawn result should not be
shown immediately. In other words, make them sync with the start
of animation.

Also
- Fix typo for scale of resolution change animation.
- Clear blast sync timeout from draw handler because
  Navbar may remove and add again while InsetsSourceProvider
  called applyWithNextDraw for it.
