  [HLSL] Fix bug in new clamp overloads (#131928)

In some cases using the newly introduced clamp overloads, when floats
were involved, clang would behave differently than DXC.
To ensure the same behavior as DXC, require that for mix scalar/vector
overloads the type of the scalar matches the type of the vector.
