Remove support for GLs without separate stencil.

As a consequence we no longer need GrDrawFace.

This effectively raises the minimum bar for non-ES OpenGL to 2.0 as there is no extension that adds the GL 2.0 separate stencil functionality. GL_ATI_separate_stencil is close but it does not have glStencilMaskSeparate.
