OpenGL: clean up firstInstance handling.

Now that we're offsetting instanceID by firstInstance via a shader
transform, we can retire the use of glDrawArraysInstancedBaseInstance[ANGLE].
These are unsupported on native ES 3.1 drivers.

Also skip some tests if IsCompatibilityMode() for things that are
expected to fail in Compat (per-draw-buffer blend state).
