ir3/compiler: Use the NIR computed offset for image store/atomics
Remove the offset computation from the a4xx/a5xx backend and use the one pre-computed in NIR by lower_io_offsets pass. No regressions observed on affected tests from Khronos CTS and piglit suites, compared to master. Unfortunately shader-db is not helpful for stats in this case. Few shaders there exercise image store or image atomic, and of those that do, most require higher versions of GLSL than 3.10, so they get skipped.
