wayland: Don't initialize OpenGL when the window flags didn't specify it

Applications that don't specify a rendering flag are likely handling Vulkan/GL themselves, so SDL loading OpenGL by default in this case is unnecessary overhead, and if a render backend requires it, the window will be recreated with the appropriate flags when the renderer is initialized.

(cherry picked from commit 9ab20251277d001ee34caeb59a7eaa54b40af622)
