[mutter/wip/carlosg/drop-caps: 4/4] backend/native: Use high priority contexts for secondary GPUs

[Carlos Garnacho <carlosg src gnome org>]

commit 4a13153da5b7610603584af548d8cf95b303e116
Author: Carlos Garnacho <carlosg gnome org>
Date:   Fri Nov 8 15:30:53 2019 +0100

    backend/native: Use high priority contexts for secondary GPUs
    
    Ensure the context requests EGL_CONTEXT_PRIORITY_HIGH_IMG, and
    that we use cogl_egl_create_context() to ensure that is honored.
