Remember last focused window position for next startup (#5529)

Implements window position persistence on macOS, similar to Terminal.app
and iTerm2. The window position is saved when it becomes main or moves,
and restored on next startup. Window position is kept within visible
screen bounds.

cc @jsumners - Would you mind giving it a try? Any feedback would be
appreciated!
