script: Do not prioritize *update-the-rendering* in `ScriptThread` message loop (#34539)

Instead run *update the rendering* at the end of every process of
gathering messages sent to the `ScriptThread`. This ensures that the
thread is in a consistent state when the update is finally run and
prevents running more than one instance of *update the rendering* per
spin of the message loop.

In addition:

- Move the *run the resize steps* implementation to `Window` and ensure
  that the realm is active when it is run.
- Profile the queueing of the resize message instead of handling it. I
  think this makes more sense as the profiling seems to be targeting
  message handling and not *update the rendering*. Additionally, it's
  difficult to profile from the context of `Window`.
