* feat: add bf8 support

* chore: remove unnecessary decltype usage

* chore: add default quant_mode to function signature as fallback

* fix: pass correct runtime pipeline params in grouped_gemm bquant kernel

Calculate has_hot_loop, num_loop, and tail_number on device side for each
GEMM problem instead of using default values. This fixes incorrect results
when different problems in the group have different K dimensions.

* chore: set default quant mode in function signature

* test: add additional test cases to cover edge case of no hotloop

* change code based on comments

* WIP: bquant preshuffle b compiles but gives numerical error

* feat(grouped_gemm_quant): bquant with preshuffleB support added to grouped_gemm example & kernel

* refactor: refactor code after merge commit

* chore: remove print statements

* test(grouped_gemm): split test cases by quant mode to reduce compilation time and add bquant-preshuffleB mode test cases
