sgemm_impl: Remove GMEM_COALESCED_A option
...
Uncoalesced GMEM accesses is verified to yield slow performance and the
relevant code is not used anymore; remove the cruft

sgemm_impl: Refactor dmem_load into one unified logic
...
Replace the confusing logic that had slightly different use of BM/BN/BK
for A and B, into one logic that accepts matrix memory layout as a
proper argument & does compile-time logic to determine the right
dimensions.

sgemm_tcore: Unpack arg params, remove threadblock_dim_y
...
thread_block_gemm is meant to be reusable, so it shouldn't assume what
the kernel arg struct looks like.
threadblock_dim_y was ambiguous and didn't match the literal name either
(it was used as # of warps that participate in a barrier).

sgemm_tcore: Split all impl code into sgemm_impl.hpp
...
This is to make thread_block_gemm a re-usable library function for GEMM
operations for use in other kernels.
