137dbefc - [WebGPU] Intel SubgroupMatrix MatMul: batched-B support (#29749)

[WebGPU] Intel SubgroupMatrix MatMul: batched-B support (#29749) - Create the Intel subgroup-matrix impl lazily in ComputeInternal (via std::call_once) instead of PrePackInternal, which only fires for constant initializers and so skipped the subgroup-matrix path for runtime/dynamic B (batched matmul). - Fall back to the generic MatMul path when N is odd: Intel's f16 subgroup-matrix B load requires an even row stride (4-byte-aligned K-rows); an odd N corrupts odd output columns. - Add batched f16 MatMul tests (matmul_large_test.cc).
