[root layer scrolls] Rebaseline 3 passing tests

These tests were all passing according to:
http://wince.sfo.corp.google.com:8766/rls

This test was recently rebaselined in
https://chromium-review.googlesource.com/c/chromium/src/+/742238
but was missing a windows expectation:
invalidation-rect-includes-newline-for-vertical-lr.html

These tests match the non-RLS expectations except they have additional
Scrolling Layer and Scrolling Contents Layers:
paint/invalidation/selection-clear-after-move.html
paint/invalidation/compositing/should-not-repaint-move-backface-hidden.html
