Implement Alexa.EventDetectionSensor for Alexa (#28276)

* Implement Alexa.EventDetectionSensor Interface

* Removed references to PR #28218 not yet merged into dev.

* Update tests to include Alexa Interface

* Guard for `unknown` and `unavailible` states.

* Fixed Unnecessary "elif" after "return"
