[CK Tile] Extend type support EightWave pipeline
## Motivation
EightWave pipeline was designed for 8 bit types. This PR extend support
for any FP type
## Technical Details
- Generalize policy to support any FP type
- Change LDS layout to fix bank conflicts. This removes all bank
conflicts in the pipeline (checked for all supported types). Remaining
bank conflicts are related to Cshuffle epilogue.
## Test Plan
Added GEMM tests with new supported types. Note that FP6 is also
supported for MX GEMM but the PR was reverted so no tests were added for
it.
