windows: Fix and simplify title bar padding (#13420)

This PR fixes the off by one pixel of the top client rect when not
maximized due to the added border. It also simplifies and properly fixes
the title bar padding problem when maximized, it is now properly taken
care of in GPUI rather then adding the padding in the UI.
