loader_dri3/glx/egl: Reinstate the loader_dri3_vtable get_dri_screen callback
Removing this callback caused rendering corruption in some multi-screen cases,
so it is reinstated but without the drawable argument which was never used
by implementations and was confusing since the drawable could have been
created with another screen.
