gl/cocoa: Store a weak reference to the `GstGLWindow` instead of the `GstGLContext` We can't rely on the `GstGLContext` to stay alive and need to keep track of it. For that we keep track of the `GstGLWindow` in a weak reference to avoid a reference cycle, and get the corresponding `GstGLContext` whenever needed. With contributions from Nirbheek Chauhan.

glwindow: add API to request a resize event on the next draw - glimagesink needs to be able to resize the viewport on aspect ratio changes resulting from either caps changes or 3d output mode changes. - Performing a glViewport outside the GstGLWindow::resize callback will not have the winsys' stack of viewports required to correctly place the output frame. Provide a function to request a resize on the next draw event from the winsys. Also track size changes inside the base GstGLWindow class rather than in each subclass. https://bugzilla.gnome.org/show_bug.cgi?id=755111
