Quake Mode - Allow Horizontal resizing

# Description of the new feature/enhancement

Currently, the Quake Mode Terminal takes up whole width of the screen and when using it on a wide monitor, this can get cumbersome to use it. Please allow horizontal resizing and allow docking it at the center horizontally - similar to the way ConEmu works.

Worth mentioning another issue already logged here #11125 which causes additional inconvenience while using wide monitor.

Start by locating the Quake Mode implementation in the Windows Terminal repository and review issue #11125 for related wide-monitor behavior. Define the intended horizontal resizing and centered docking behavior based on the issue description, then verify that Quake Mode can be resized horizontally and docked at the center without regressing its existing behavior.
