Add built-in macros to identify whether a trigger was created from an LLD trigger and to return the corresponding Trigger Prototype Name.

Currently this information is not exposed by any {TRIGGER.} or {EVENT.} macro and can only be retrieved through API queries or manual tagging.

Having these macros would allow actions, notifications, and integrations to properly differentiate LLD-based triggers. This removes the need for workarounds and enables cleaner automation.
