feat(lfa): add initial implementation for LFA_ACTIVATE
This patch introduces the overall handling of the LFA_ACTIVATE call,
including input validation and invocation flow.
While this covers the core implementation, per-component-specific
handling will be developed in a separate patch. The respective
component callbacks are invoked as part of this logic.
