radeon: more fixes for compressed textures

- fix not respecting required hardware stride with compressedTexImage -
  this fixes #22615.
- make sure correct stride is used in various places
- fix stored miptree never matching with a TexImage call with compressed
  texture
- don't always store data with compressedtexsubimage at offset 0,
  and actually use the supplied pixel data... (untested)
- make sure rows for compressed texture handling are rounded up not down

Note that trying to access stored compressed textures in hardware miptrees
from core mesa (get_compressed_teximage, swrast fallbacks) can't work correctly,
since RowStride isn't really set to anything useful, plus some places (at least
get_compressed_teximage) assume this data has native stride and no padding.
