WM: use different drag thresholds for mouse/tablet events

Now a small threshold is used for mouse input,
avoiding delay when gizmos are activated on drag.

Tablet input threshold remains unchanged since
it's easier to make small movements when using a tablet.

A larger threshold for non-cursor input is now used (typically keyboard)
which improves usability when the "Pie Menu on Drag" key-map preference.
