Revert of Update GPU memory buffers to use StrideInBytes internally.

Revert of Update GPU memory buffers to use StrideInBytes internally. (patchset #4 id:60001 of https://codereview.chromium.org/806653006/)

Reason for revert:
This seems to be causing a lot of redness, e.g.
http://build.chromium.org/p/chromium.win/buildstatus?builder=Win7%20Tests%20%281%29&number=35371

Original issue's description:
> Update GPU memory buffers to use StrideInBytes internally.
>
> Tile texture compression will add support for GPU memory buffer formats
> that use less than a byte per pixel.
>
> This CL prepares GPU buffers for this by using a new function
> StrideInBytes instead of relying on bytes per pixel calculations when
> calculating the number of bytes needed to store a certain number of pixels.
