Allow enabling support for both the X11 and Wayland backends.
This in turn needs reorganizing how desktop GL or OpenGL ES is chosen,
as it no longer can depend on whether Wayland support is enabled: the
BR2_PACKAGE_HAS_LIBGL and BR2_PACKAGE_HAS_LIBGLES variables are both
checked, and ENABLE_GLES2 is set only if the package providing OpenGL
claims only GLES is supported; otherwise desktop GL is preferred. This
matches the existing logic.
The existing comment indicating that only one of both windowing systems
can be enabled was wrong: the same WebKitGTK build can target both
X11 and Wayland at the same time, as long as GTK itself has been built
accordingly. Enabling both is the approach taken by most Linux
distributions, and has been supported for years.
