[CK_TILE] Add Bquant to Grouped Gemm (#3063)

Browse Source 
* update test cases

* format codes

* use GTEST_FAIL

* add bquant to grouped_gemm

* fix a bug in test_grouped_gemm_util

* skip test when use wmma on grouped_quant kernel

* add tensorwise quant in grouped gemm

* fix example issue

* update test cases

* format codes

* fix a bug in test_grouped_gemm_util

* tests(quant_grouped_gemm): add unit tests to cover bquant in grouped_gemm

* Update test/ck_tile/grouped_gemm_quant/test_grouped_gemm_util_quant.hpp

Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com>

* Update example/ck_tile/17_grouped_gemm/quant_grouped_gemm.hpp

Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com>

* 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

* chore: clang formatting
