question: why this change is needed? Did merge become synchronous?

Yes. Merge sort now has calls to cudaGridDependencySynchronize, which cause the benchmark to crash if I were to use no_batch.

Make PDL available with CTK 12.0
e05cfe2 
For some reason, I made PDL available with CTK 11.8 in NVIDIA#3114, but it seems the feature is only available starting with CTK 12.0.

Enable PDL for DeviceMergeSortBlockSortKernel
4fe1beb 
The kernel already contains a call to _CCCL_PDL_GRID_DEPENDENCY_SYNC,
but PDL was not enabled when launching it. This was missed in NVIDIA#3114.
