[CK TILE] Stream-K tile partitioner (#2708)

* initial commit for skeleton code

* replaced skeleton code with old streamk b2c map functions from old CK, still need to clean up the code

* fixed up code to match CK Tile convention: data type changes, naming changes, etc.

* change for num_sk_blocks data type

* formatting fix

* minor fixes

* moved reduction argument to template

* resolved comments from PR review: standardizing naming, pruning unneeded code

* resolve errors from merge of device op PR: moved enum to common file

* switching to uint32_t due to implementation constraints: divmod only takes uint32_t and mixing signed and unsigned types causes problems

* unsigned type fix

* add const qualifier

* added documentation for template parameters

* documentation edit
