Create cc::TilingData based on WebCore::TilingData.

This is a direct port of the TilingData class from the WebKit repo, found in:
Source/WebCore/platform/graphics/gpu/TilingData.h|cpp

Previous commits from non-google folks have been:
- ossy replacing the non-copyable macro (which is not present here).
- hyatt replacing right()/bottom() with maxX()/maxY() (we use right()/bottom() again here, with gfx::Rect instead of IntRect).
- mitz using ASSERT_UNUSED instead of ASSERT guarded on NDEBUG (we use DCHECK instead here).

Covered by existing tests; this replaces the use of WebCore::TilingData with the new cc::TilingData.
