Move stencil mask validation to before the draw. ANGLE (and WebGL) restrict the back and front stencil masks on draw, due to D3D restrictions. We would previously only validate this if the stencil was enabled in D3D9. In D3D11 we would validate the stencil masks even if the stencil is disabled, which is the behaviour the spec suggests. Moving the error check to before the draw also prevents any issue with interrupting a draw call mid-way through.
