* Initial implementation: - add new thread group transfer supporting transpose instruction - refactor AB transfer to switch between thread and wave tiles methods * Add some comments and remove explicit wave and lane calculations * Remove compiler option for performance * fp16 example: use tuned instance * Missing cleanup * Integrate wave transfer in existing gemm and batched gemm instances * Add fast instances * extend implementation for 8 bit datatypes packed types not supported * Address review comments * Optimize pipeline v1 and re-introduce compiler option * Disable wave tile approach for b scale gemm * Fix for clang20 * Avoid code duplication of amd_global_load_transpose_to_vgpr function
