Bug 1522714 - Update APZCTreeManager::ComputeTransformForNode() with changes corresponding to the AsyncCompositionManager changes for containerless scrolling. r=kats

Details

For compositor hit testing to work correctly inside fixed-position content, the adjustments made in AsyncCompositionManager for rendering purposes need to be applied to GetAPZCAtPoint for hit-testing purposes as well.

Specifically, we make adjustments to the transform used for:

  • layers with the RCD-RSF APZC
  • the async zoom container layer
  • layers fixed w.r.t the RCD-RSF

Depends on D18113

Let's mark it as "disabled", as containerless scrolling is not going to be enabled in 66.
