etnaviv: use padded width/height for resource copies

etnaviv: use padded width/height for resource copies

When copying a resource fully we can just blit the whole level. This allows
to use the RS even for level sizes not aligned to the RS min alignment. This
is especially useful, as etna_copy_resource is part of the software fallback
paths (used in etna_transfer), that are used for doing unaligned copies.
