[mutter/wip/carlosg/drop-caps: 7/7] backend/native: Use high priority contexts for secondary GPUs

[Carlos Garnacho <carlosg src gnome org>]

commit 3fa39840e1c23a8008fe025d4d9a5d062bd3e122
Author: Carlos Garnacho <carlosg gnome org>

    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.
