Add RDNA-specific MXFP4 matmul_ogs configs for GPT-OSS MoE shapes. The configs were selected from an exhaustive search on both RDNA3 and RDNA4. Following the existing CDNA4-specific path, add tuned configs for RDNA by choosing different tile shapes for small and large M. Backport of triton-lang#10810.
