Block SetContinuousInvalidate during BeginImplFrame

This is moving some of BrowserViewRenderer::block_invalidate_
logic into content SynchronousCompositor. In short, during
DemandDraw, SynchronousCompositor will only call
SetContinuousInvalidate once at the very end of the draw, to
prevent the unnecessary state flip leads to an unwanted
invalidate.

This logic originally lives in BrowserViewRenderer. Moving it
to SynchronousCompositor will allow HardwareRenderer to be
refactored out of BrowserViewRenderer
