gpui_macos: Fix traffic lights animation during fullscreen exit (#64339)

# Objective

Fixes #64050

Going out of fullscreen on MacOS currently gives the traffic lights a
janky animation. This seems to be a timing issue during ownership
transfer of traffic light rendering from AppKit to Zed.

## Solution

Add an additional boolean flag (yes, sad), which keeps track of whether
the animation from full screen to windows has completed.

## Testing

Tested this on a mac, animation is now buttery smooth.
