[nickodei]

GitHub Issue: closes #19131

PR Type

What kind of change does this PR introduce?

• Refactoring (no functional changes, no api changes)

What is the current behavior?

Most sensors used an TypedEventHandler field and had duplicated logic on the event handling.

What is the new behavior?

Refactoring to use StartStopTypedEventHandler that encapsulates the logic for event-handling.
This is now used in the sensor classes instead.

I also saw that on a lot of sensor classes, the GetDefault() Method was duplicated as well. In LightSensor we use Lazy<LightSensor?> _instance. Should this also be done for the other sensors? I wasn't sure about it.

That can be done as separate PR - I guess using Lazy for all sensors might be the best way to unify them all (and it will clean up all the _initializationAttempted variables too).
