[CK_TILE] Adding steps in Stream-K Tile Engine (#6511)

## Motivation
This PR adds step functionality to the Stream-K instance generator in
Tile Engine in order to quickly generate instance configurations within
a certain max/min range. To complement this, the Stream-K Tile Engine
validation file has been updated for more rigorous validation of
generated instances.

## Technical Details
- Added _generate_values helper to support min/max/step range-based tile
config generation, matching Universal GEMM
- Added validate_gemm, validate_whole_wg_cover_configuration,
validate_cshuffle_epilogue_distribution, and other supporting functions
to the Stream-K validation utils, aligning with the validation already
present in the Universal GEMM

## Test Plan
Tested using the generation in CK Tile Engine

## Test Result
All instances were generated and validated correctly.
