Revert "Support Canvas Clip on Blit Framebuffer"

This reverts commit 1f1646dd861c4b78f0a935b45f7802c787dac198.

Reason for revert: Vulkan build failures, many non-Vulkan test failures.

Original change's description:
> Support Canvas Clip on Blit Framebuffer
>
> The previous fix to blit framebuffer didn't take cases where
> the canvas had a clip applied into account. Fix and update
> the unit test to add this case.
>
> AND
>
> Respect kRectsMustMatchForMSAASrc_BlitFramebufferFlag in dst setup
>
> Crurently, when preparing a texture for blitFramebuffer, we ignore the
> kRectsMustMatchForMSAASrc_BlitFramebufferFlag, and may attempt to
> copy from one src rect to a different dst rect.
>
> This change updates initDescForDstCopy and setupDstTexture to allocate
> larger textures if necessary and accomodate this flags requirements.
