UI: Skip Internal Operators For Idle Status Bar

During idle time, just moving your mouse into an editor, the Status Bar
only shows operations attached to mouse events. Hovering into
Properties shows an item on the left mouse called "Set Active
Modifier". This is always shown because it is an internal operator
always running in that area. This PR just skips OPTYPE_INTERNAL
operators for this idle display.
