renderer-native: Ensure all planes support EGL config format

For secondary GPU rendering contexts we currently might choose an EGL
config with a format which is not supported on all primary planes. The
renderer is created when a GPU is detected and lighting up outputs and
thus assigning CRTC and primary planes can happen at any point after
that. This means we have to make sure that all possible plane
assignments will work with the rendering context when we create it.

Closes: https://gitlab.gnome.org/GNOME/mutter/-/issues/3235
Fixes: cc7bca073 ("crtc/kms: Dynamically assign primary and cursor planes")
