I don't see the point why we want to use context0 to do transfer.
If we always use original context to do transfer, then we can
avoid sync between contexts for mobile GPU.

We want to move resource lookup up from vrend to virglrenderer for
transfers. Depending on whether ctx_id is specified, we need to
pass a virgl_resource or a pipe_resource down. Let's move handle
out of vrend_transfer_info first.

virgl_renderer_transfer_write_iov doesn't work for YUV buffers, since
it's based on glTexSubImage.
We assume the YUV image is not disjoint, since that's currently what
Mesa gbm supports.
For RGBA buffers, this will also eliminate a copy in the cases
where the gbm_bo_map(..) implementation doesn't use a shadow buffer
[i915, mediatek, rockchip].

Rename VREND_RESOURCE_STORAGE_IOVEC to
VREND_RESOURCE_STORAGE_GUEST_ELSE_SYSTEM and introduce
VREND_RESOURCE_STORAGE_GUEST. The former is used as storage for query
buffers, and the latter will be used in upcoming commits for staging
buffers.
