Fix T62875: Tooltips behave erratically with view gizmos

Improvements to behavior for gizmo tool-tips.

- 2D gizmos no longer cancel tool-tips on cursor motion
  (matching the behavior of UI widgets).

- 3D gizmos still close on motion since 3D gizmos may have a large
  on-screen area which would cause them to stay visible even after the
  cursor has been moved a large distance. The motion threshold is used
  so they don't close on unintended cursor motion.

- Changing highlighted gizmo now cancels the tool-tip & resets the timer.
