Remove unparentsOffscreenTiles logic in TileController
https://bugs.webkit.org/show_bug.cgi?id=167823
Reviewed by Tim Horton.
Source/WebCore:
Give all TileGrids the "unparents offscreen tiles" behavior. This was enabled for
only the page tiles in WK2 on Mac and iOS, but there's no reason to not use it for
tiled composited layers also.
Also use more modern C++ idioms in a few places.

Drive-by fix: make sure we put the tiled scrolling indicator's layer back when switching tabs.
