Revert of Use transfer buffer for BatchAtlas texture copies (patchset #9 id:160001 of https://codereview.chromium.org/1888473002/ )

Reason for revert:
Lots of sync issues with paths and text.

Original issue's description:
> Use transfer buffer for BatchAtlas texture copies.
>
> Sets up use of transfer buffer (if available) to do one-copy transfers.
> Get transfer buffers working properly in GL.
> Implement GrVkGpu::onTransferPixels.
> Check caps to ensure we can create a transfer buffer.
>
