[iOS WK2] Make -webkit-overflow-scrolling be a no-op
​https://bugs.webkit.org/show_bug.cgi?id=196803
rdar://problem/49078202

Reviewed by Antti Koivisto.

Source/WebKit:

Flip LegacyOverflowScrollingTouchEnabled to false.

  • Shared/WebPreferences.yaml:

LayoutTests:

Rebase some tests, if I thought that non-stacking context overflow was interesting.
For others, make overflow be stacking context by adding z-index.
Add <!-- webkit-test-runner [ internal:AsyncOverflowScrollingEnabled=true ] --> to those that
need it.
