WM: Add 'Confirm On Release' option for WM_OT_radial_control

Adds a new property called "Confirm On Release" that does what it says,
confirm the action without having to do left-click or to press any other
extra-key which concludes in a more dynamic and efficient way of changing
brush size or strength for example, especially for tablet users.
