Set correct uniform size for Metal.

There are two fixes here. The first pads out the uniform buffer to
match the alignment of the largest element in the buffer, as required
by Metal. The second ensures that the RTHeight uniform is only added
to the shader if required by the program inputs, as otherwise it wasn't
being included in the uniform data.
