Gaurav Garg 517b5ddbf0 CUDA: Improve flash decoding kernel GPU occupancy for BS=1 case (#12183) 
- Find out active blocks per SM using cudaOccupancyMaxActiveBlocksPerMultiprocessor API. Use this value to determine the optimal parallel_blocks value.
- Prefer vector flash attention kernels over MMA kernel for BS=1

Fixes Issue: #12182
