HLSL: allow promotion from 1-vector types to scalars, e.g, float<-float1
Previously, an error was thrown when assigning a float1 to a scalar float, or similar for other basic types. This allows that. Also, this allows calling functions accepting scalars with float1 params, so for example sin(float1) will work. This is a minor change in HlslParseContext::findFunction().
