Add option to disable CursorWrap when on a single monitor. (#45303)

## Summary of the Pull Request
CursorWrap wraps on the outer edge of monitors, if a user is swapping
between a laptop and docked laptop with external monitors the user might
want to only enable wrapping when connected to external monitors, and
disable when only on the laptop.

## Detailed Description of the Pull Request / Additional comments
Currently CursorWrap will wrap around the horizontal/vertical edges of
monitors, if the user has more than one monitor the outer edges are used
as wrap targets, if the user only has one monitor (perhaps a laptop)
wrapping might be temporarily disabled until additional external
monitors are added (such as being plugged into a dock or using a USB-C
monitor).

The new option will disable wrapping if only a single monitor is
detected, monitor detection is dynamic.

## Validation Steps Performed
Validated on a Surface Laptop 7 Pro (Intel) with a USB-C External
Monitor.
