HIP: add GGML_HIP_MMQ_MFMA option to allow disableing the MFMA path. (#14930) This is useful for testing for regressions on GCN with CDNA hardware. With GGML_HIP_MMQ_MFMA=Off and GGML_CUDA_FORCE_MMQ=On we can conveniently test the GCN code path on CDNA. As CDNA is just GCN renamed with MFMA added and limited use ACC registers, this provides a good alternative for regression testing when GCN hardware is not available.
