[CK_TILE] Grouped gemm quant tensor layouts (#3414)

* feat: add RRR, CRR, CCR layouts for a/b quant grouped gemm tests and examples. Refactor example setup to improve compile time

* chore: split out bquant preshuffle test, and reduce tile size to 128 to temporarily solve slow compile times

* chore: set m/n warp tile to 16 as configurations with 32 seem to have some support problems

* fix: missing check for transposed load in bquant pipeline

* chore: lower unit test tensors dimensions a bit for faster tests

* chore: set grouped gemm example M/N warp tile to 16
