Revert of skia: Add support for CHROMIUM_image backed textures. (patchset #17 id:340001 of https://codereview.chromium.org/1623653002/ )

Reason for revert:
New unit test is failing on Windows ANGLE bots:
http://build.chromium.org/p/client.skia/builders/Test-Win8-MSVC-ShuttleB-GPU-HD4600-x86_64-Release-ANGLE/builds/1866/steps/dm/logs/stdio

Original issue's description:
> skia: Add support for CHROMIUM_image backed textures.
>
> I created a new abstract base class TextureStorageAllocator that consumers of
> Skia can subclass and pass back to Skia. When a surface is created with a
> pointer to a TextureStorageAllocator, any textures it creates, or that are
> derived from the original surface, will allocate and deallocate storage using
> the methods on TextureStorageAllocator.
