wined3d: Clear the graphics pipeline key stencil test state when the stencil test is disabled.

The state itself is ignored in this case, but could still cause additional
pipeline variants to be created. That's mostly a consideration for Direct3D 9
and before, since Direct3D 10 and 11 already normalise disabled stencil test
state themselves.
