[BlinkGenPropertyTrees] Update expectations

This patch adds an expectation for:
  paint/invalidation/scroll/composited-iframe-scroll-repaint.html
This is needed because ancestor clipping layers are not created for
BGPT (see: https://crrev.com/556569).

images/cross-fade-invalidation.html has been marked as failing and a
bug has been filed: https://crbug.com/874672.

compositing/rtl/rtl-fixed-overflow-scrolled.html has been marked as
failing. This is likely related to https://crrev.com/583398

Two sticky tests started failing. This is likely caused by
crrev.com/581763. Filed https://crbug.com/874675 and marked as failing.

Bug: 836886
