Rename Mac's TileCache to TileController, and WebTileCacheLayer to WebTiledBackingLayer
https://bugs.webkit.org/show_bug.cgi?id=111779

Reviewed by Tim Horton.

"TileCache" was a name conflict in downstream code, so rename it to TileController.
The layer that has a TileController is now a WebTiledBackingLayer (which fits with
the TiledBacking API that TileController exposes).

Also renamed the flags in PlatformCALayer to match.

Rename only, no behavior change.
