gallium: Plumb the swap INVALIDATE_ANCILLARY flag through more layers.

v2: Instead of telling the driver that the window system ancillaries have
    been invalidated (when the driver doesn't know which of its buffers
    are the window system's!), introduce a method for invalidating
    specific surfaces.
