Revert of Re-land: ui: Add custom stride support to GLImageMemory. (patchset #4 id:60001 of https://codereview.chromium.org/1403283007/ )

Reason for revert:
Still failing to compile.

Original issue's description:
> Re-land: ui: Add custom stride support to GLImageMemory.
>
> This improves our support for shared memory pools by allowing
> clients to create GLImages with a stride that is larger than
> the row length of the image.
>
> This makes it possible to import a buffer with a stride that
> doesn't match the aligned row size. However, support for
> mapping of such a buffer is not provided by this patch.
>
> BUG=549781
> TEST=gl_unittests --gtest_filter=GLImageSharedMemoryPool/GLImageCopyTest/0.CopyTexImage
