Give TiledBacking a TiledBackingClient that allows a client more knowledge of
tile painting
https://bugs.webkit.org/show_bug.cgi?id=269268
rdar://122850594
Reviewed by Tim Horton.
Introduce TiledBackingClient, a weakly held client of TiledBacking that gets
informed
when a tile is repainted or removed, and when all tiles are invalidate.
UnifiedPDFPlugin will use this as a basis for caching.
The client is informed about events per tile using TileGridIndex and TileIndex
to
identify tiles; TileGridIndex is 0 for the main tile grid, and 1 for the
optional zoomed-out
tile grid.
