ggml-webgpu: enable FLASH_ATTN_EXT on browser without subgroup matrix (#22199) * ggml-webgpu: add tile flash attention fallback * ggml-webgpu: add new fields and discard usage of mnk for tile version * ggml-webgpu: modify the vec path to discard the mnk parameter * ggml-webgpu: enable flash attention vec and tile version for broswer * ggml-webgpu: stagging KV for flash attention tile version * formatting * turn on subgroup uniformity check * remove Q_TILE as it is always 1 for vec path * make row_max and exp_sum to local register * make different bindings with same underlying buffer to have the same usage flags * move path selection into the shader library and have the host consume a single flash-attn decision object. * turn off skip_validation and address buffer overlapping when nwg==1 * formatting * merge binding when kv overlap
