gl/msaa: Rely on the stencil buffer to cache the clip
When using a texture surface the depth/stencil buffer is private to
cairo so we can rely on the fact that any previously painted clip is
still valid.
We also only scissor when there's a previously painted clip on the
stencil buffer, otherwise we disable the scissor test. This fixes a few
test cases.
