Akarshan BiswasandGitHub b54cb2e3d0 sycl : add flash-attn support for head size 512 (#21654) 
* sycl : add flash-attn support for head size 512

This patch extends the SYCL Flash Attention implementation to support head sizes (DKQ/DV) of 512.

Changes:
- Added DKQ/DV 512 cases to both tile and vector Flash Attention kernels.
- Updated kernel selection logic to allow vector kernels for head sizes up to 512 (previously 256).
- Removed unused/redundant AMD and RDNA-specific configuration functions in `fattn-tile.hpp`.
- Refactored `ggml_backend_sycl_buffer_init_tensor` to use a switch statement for clearer tensor extra buffer initialization.
- Added necessary template instances for the new 512 head size across various quantization types.

* remove defunct mxfp4 reorder from setting buffer type
