Message:

Use larger tiles when possible to reduce per-tile painting overhead
​https://bugs.webkit.org/show_bug.cgi?id=154985

Reviewed by Zalan Bujtas.

Source/WebCore:

r197541 inadvertently missed FrameView changes that push scrollability data
onto the TiledBacking, so didn't actually change behavior (hence the 512x512 tiles
in the failing tests).

Also remove m_tileSizeAtLastRevalidate from TileGrid; it's replaced by a simpler test.

     8        r197541 inadvertently missed FrameView changes that push scrollability data
     9        onto the TiledBacking, so didn't actually change behavior (hence the 512x512 tiles
     10        in the failing tests).
     11
