meta: Make MESA_META_DRAW_BUFFERS restore properly
A meta begin/end pair with MESA_META_DRAW_BUFFERS will change visible GL state. We recreate the draw buffer enums from the buffer bitfield, which changes GL_BACK to GL_BACK_LEFT (and GL_FRONT to GL_FRONT_LEFT). This commit modifes the save/restore logic to instead copy the buffer enums from the gl_framebuffer and then set them on restore using _mesa_drawbuffers(). It's not clear how this breaks the benchmark in 82796, but fixing meta to not leak the state change fixes the regression. No piglit regressions.
