sgemm_tcore: Fix addr gen for GMEM->SMEM for M-major A

This fixes correctness for TRANSPOSE_AT_PRODUCE/COLUMN=0/0, provided the
matrices are already stored in the correct layout in GMEM.

sgemm_tcore: Support data move for fp16-packed elements
...
Since core does not support memory accesses to non-word-aligned
addresses, pack fp16 elements in pairs into fp32 values, and do regular
tile movement with conditionally compressed column dimensions.
Perf seems to stay the same for fp32 256x256.
