tint: workaround DXC bug with splatted vector constant storage buffer args

This is the same as crbug.com/tint/1976, except that the DXC bug also
occurs on storage buffer Store calls. DXC fails to compile if the vector
argument is a signed integer splatted constant (though, in this case, it
needs to be non-zero). This change implements the same workaround:
explicitly cast the arg to the expected vector type.

See the upstream bug: https://github.com/microsoft/DirectXShaderCompiler/issues/5389
