Auto merge of #29745 - mrobinson:compositor-side-scroll-tree, r=mukilan

Add a compositor-side scroll tree

This will allow the compositor to properly chain scrolling requests up
when a node has reached the extent of the scroll area. In addition, it
removes the use of the deprecated WebRender `scroll()` API. This fixes
scrolling on servo.org.
