Compositor API: Don't leak OpenGL textures when running multi-threaded

If a client destroyed buffers, they would not get deleted because the event
would be handled on the GUI thread without a valid OpenGL context. I.e: you
would see the following output:

    QOpenGLTexturePrivate::destroy() called without a current context.
    Texture has not been destroyed

Work around it by keeping a list of buffers that have been orphaned and delete
them whenever we have a valid OpenGL context.
