[WebGPU] Regenerate WGSL in-tree golden fixtures to match current templates (#32115) ### Description Regenerates the WGSL in-tree golden fixtures. No production code changes; every file touched lives under onnxruntime/test/in_tree_golden/. Generated with: UPDATE_WGSL_GOLDEN=1 python tools/python/wgsl_template/test/run_tests.py Before: Ran 87 tests, FAILED (failures=2) After: Ran 87 tests, OK Three fixtures are new or rewritten: subgroup_matrix_gemm_8x16x16, subgroup_matrix_matmul_8x16x16, subgroup_matrix_matmul_pad_b. The remaining churn in im2col_matmul.h, oihw_to_ohwi.h, pad.h and string_table.h is index renumbering: the generator emits one globally numbered string table, so adding literals shifts every downstream __str_N index. Those files are unchanged once the indices are normalized. ### Motivation and Context The in-tree golden test compares the whole generated tree against committed fixtures, so it fails on main today. The subgroup-matrix templates were added or rewritten without regenerating the goldens. Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com>
