trigger: keep state of if a trigger is currently registered

Since a trigger can be referenced even when is was "unregistered" in
other part of lttng-sessiond, namely the action executor queue, we must
keep track of the registration state.

This will allows us to easily skip any actions to be executed
if the associated trigger is "unregistered" at the moment of
execution. This is implemented in a following patch.
