v3d: Implement texture_subdata to reduce teximage upload copies.

This lets us store the non-PBO glTexImage data directly into the tiled
image without making an extra untiled memcpy for the gallium transfer.
Improves 1024x1024 TexImage perf by ~19%, mostly from not thrashing around
in the kernel mapping and unmapping the transfer's temporary area.
