Triggering callbacks from within BMS scripts

[Peepo-Juice]

Request

Provide an API similar to this:

trigger_event("EventHandlerLabel", script_entity, args, script_id)

Which leads to the provided event handler being triggered. Target capabilities should match the Recipients enum.

Describe the solution you'd like

• run_event_deferred: executes when the current callback ends. No frame delay
• run_event: executes immediately, possibly returning a result.
• Take into account the possibility that the triggered event might also lead to another event being triggered. If it can lead to a chain like that, then we also need to take into account infinite loops.

This should now be possible, so long as we are not triggering a callback in the same script, due to the simplifcation of the handler context structures.
