Jonas Ådahl 634c948fc6 native: Add headless mode using surfaceless EGL context
This eliminates the need for any render node or device nodes, thus can
be used without any graphics hardware available at all, or with a
graphics driver without any render node available.

The surfaceless mode currently requires EGL_KHR_no_config_context to
configure the initial EGL display.

This also means we can enable the native backend tests in CI, as it
should work without any additional privileges.
