Remove MainThreadScrollingReasons::kHasClipRelatedProperty

We no longer need to skip composited scrolling for css clip and
clip-path since (perhaps) BlinkGenPropertyTrees.

Automatic update from web-platform-tests
Remove MainThreadScrollingReasons::kHasClipRelatedProperty

We no longer need to skip composited scrolling for css clip and
clip-path since (perhaps) BlinkGenPropertyTrees.

In compositor, when we hit test on a layer with special clip/mask,
we'll still fallback to main thread hit testing/scrolling because only
the main thread knows which area is hit testable. This is achieved by
cc::LayerTreeHostImpl::IsInitialScrollHitTestReliable() returning false.
