Mouse Button-Click De-Bouncer

### Description of the new feature / enhancement

Many mice and trackballs fail to handle high-speed contact bounce as the hardware ages. A system-level debounce function would eliminate the need for frequent hardware replacement or repair.

### Scenario when this would be used?

If a pointing device (e.g., Logitech M570 trackball) begins registering false double-clicks, this feature would allow for an adjustment of the interrupt handler for mouse button-down or button-up.

### Supporting information

There are a few quick & dirty debounce routines available, but I haven't found one that works well. It seems that this condition has to be addressed at a very low level for it to work reliably. Since the primary button is used far more than the right-click button, the left button is likely to be the main problem for most usage scenarios.

Start by locating the mouse input path and the interrupt handling for mouse button-down and button-up events; the issue does not name files, tests, or an existing PowerToys entry point. Determine where a system-level debounce could belong and define done as reliably preventing false double-clicks without disrupting intentional clicks.
