feature request: Move the close/minimize/maximize buttons to the top-left of the custom window frame on macOS

[ryan-roche]

Request

The standard layout for macOS windows is to have the close, minimize, and fullscreen buttons on the top-left of the window, in that order. When using the custom frame option on the desktop client, the window controls appear on the top-right, Windows-style. Revolt's window controls should follow that standard on macOS.

Reasoning

Plenty of other programs that use their own custom menu bars- like Visual Studio Code, for example- still use the native macOS window control buttons in the standard macOS layout.

Mockup

I've attached a roughly-made mockup below.
