[CK Tile] Spatially local GEMM tile partitioner. (#1843)

Browse Source 
* Add spatially local tile partitioner

* Use 1D Grid size & create partitioner object.

* Docs & use 1D partitioner in example.

* Clang format.

* Change kernel grid size

Now: X is the # of output C-tiles,
     Y is the batch count
     Z is the splitK

* Formatting & more doc.

* Clang format.

* Fix batched gemm test. Use 1d partitioner.

* Move condition.

* FIx ctor.

* clang-format.
