Lighthouse: Fix QGLContext::currentContext for systems with limited

resources. The example plugins EGLFS uses only 1 native
context. Make sure that we only use this 1 context, and that we dont
wrap it in many different QPlatformGLContexts or QGLContexts instanses.

This change also removes the QPlatformWindow link which was made in the
initial QPlatformGLContext change. Lighthouse has to support situations
where a context isnt bound to a QPlatformWindow.
