Clamp stencil reference value to D3D11 8-bit limitations.

D3D11 can only mask 8 bits of a stencil reference value, so the
upper bits are ignored. GL, however, expects the reference value
to be able to scale to 32-bits.

We will expect to fail certain edge cases where the reference value,
and mask, both use particular 9+ bit values.
