Added ImGuiKey_MouseXXX aliases. (#4921) Reworked SetItemUsingMouseWheel() to use this for ActiveId. (#2891)

Browse Source 
The rework of SetItemUsingMouseWheel() is half-complete since there's a HoveredIdUsingMouseWheel component. This will however be totally cleaned when we transtion to InputOwner system.
