Closes#30513
- Abstract away common wrapper component to `platform_title_bar`.
- Use it in both zed and rules library.
- For rules library, keep traffic like only style for macOS, and add
custom title bar for Linux and Windows.
Release Notes:
- Added way to minimize, maximize, and close the rules library window
for Linux.
There's probably more to do to fully make the transition, and we'll
still debate a bit internally whether this is the name, but just opening
this PR up now for visibility.
Release Notes:
- N/A
