Add one dx::linalg Matrix::Splat and Matrix::Store execution smoke alongside the existing private-builtin operation test. Reuse the same host parameters, execution path, and exact oracle so the new case isolates embedded public-header availability and lowering.

Summary
dx::linalgSplatStore execution smoke alongside the existing private-builtin testMatrix::SplatandMatrix::Storethrough the embedded<dx/linalg.h>headerRationale
Operation-level HLK tests continue to use private builtins for precise DXIL coverage. This single public-API smoke proves that the shipped header is available to the ExecutionTest compiler path and lowers to the expected LinAlg operations without requiring a corpus-wide migration.
The builtin and public shaders produce identical LinAlg matrix types, calls, operands, and matrix metadata; only the container shader hash differs.

Please confirm the public-header test is sufficient as the one end-to-end API smoke and that the existing builtin test remains the canonical operation-level coverage.
