gallium/radeon: add depth/stencil_adjusted output to surface computation

This fixes a rare bug with stencil texturing -- seen on Polaris and Tonga,
though it's basically a function of the memory configuration so could affect
other parts as well.

Fixes piglit "unaligned-blit * stencil downsample" and various
"fbo-depth-array *stencil*" tests.
