This PR adds WebAssembly SIMD TRSM kernels for
WASM128_GENERICand wires them up forSTRSMandDTRSM.The overall blocked TRSM structure is unchanged. This keeps the existing generic control flow and specializes the small triangular solve path for WASM friendly fixed-size cases used inside the kernel.
To make the target-specific selections take effect reliably, this also changes the base
kernel/wasm/KERNELdefaults to allowWASM128_GENERICoverrides for GEMM/TRSM kernel entries.In local direct WASM benchmarking with Pyodide/Emscripten, direct
cblas_strsmimproved over the current genericWASM128_GENERICpath by about2.3x–3.4xacrossLN/LT/RN/RTcases for the sizes tested (128, 160, 192, 256, 384). Directcblas_dtrsmimproved by about1.6x–2.2xacross theLN/LT/RN/RTcases tested (128, 192, 256, 384).
