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.
