[debugger] Pass break reason for interrupt along with BreakRightNow

This explicitly passes along the break reason when requesting a pause
that is handled via an interrupt. Pushing the break reason is not
enough (as done before), as the reason may be used and consumed on
another pause call that triggers a setPauseOnNextCall.
