Make TestEventTrigger delegate testable and extensible (#31724)

* Make TestEventTrigger delegate testable and extensible

- Make TestEventTriggerDelegate base class manage multiple sub-handlers.
- Add unit tests for TestEventTriggerDelegate
- Introduce an interface for generic TestEventTrigger handlers
- Add Clear() method to Intrusive list to remove everything.
- Document the fact that `emberAfHandleEventTrigger` should NOT be used
- Update all examples as needed.
  - Renumber OTA and SmokeCO testevent trigger prefix to match new Matter 1.3
    standard (first 16 bits == cluster ID being tested).
  - Clean-up dead code
  - Register OTA test event handler as intended.
- Add TODOs for platforms to clean-up TestEventTriggerDelegate registration.
- Updated BOOLCFG tests to use `--hex-arg` for PIXIT since `--int-arg` is too
  confusing with complex keys.

Issue #31723

Testing done:
- EEVSE Python tests using event triggers pass
- SMOKECO YAML tests using event triggers pass
- BOOLCFG Python tests using event triggers pass
- TC_TestEventTrigger passes
- New unit tests pass

* Fix merge issue

* Restyled by clang-format

* Fix uninitialized variable access

* Fix Ameba/Silabs build

* Fix CopyString bound

* More fixes of Ameba/Silabs build
