Fixes #8713

This stores the last closed state of the quick terminal by screen
pointer. We use a weak mapping so if a screen is unplugged we'll clear
the memory. We will not remember the size if you unplug and replug in a
monitor.

You can now resize the quick terminal both vertically and horizontally. To incorporate adjusting the custom secondary size on the quick terminal we needed to have the ability to resize the width (if from top, bottom, or center), and height (if from right, left, or center). The quick terminal will retain the user's manually adjusted size while the app is open. A new feature with this is that when the secondary size is adjusted (or primary if the quick terminal is center), the size will increase or decrease on both sides of the terminal.

Added C bindings for the already existing quick-terminal-size
configuration. Created a new QuickTerminalSize struct to hold these
values in Swift. Updated the QuickTerminal implementation to use the
user's configuration if supplied. Retains defaults. Also adds support to
customize the width of the quick terminal (height if quick terminal is
set to right or left).
