[extensiontest] Remove StatusWatcher helpers (#11044)

Ex. Adding a feature - Explain what this achieves.-->
#### Description

Removes some helpers from `extensiontest` related to the componentstatus
package.

As the following Github searches show, these symbols are not used by any
public package outside of opentelemetry-collector and its forks:
-
[NewStatusWatcherExtensionCreateSettings](https://github.com/search?q=NewStatusWatcherExtensionCreateSettings+language%3AGo+-is%3Afork&type=code)
-
[NewStatusWatcherFactory](https://github.com/search?q=NewStatusWatcherExtensionFactory+language%3AGo+-is%3Afork&type=code)

Therefore, I think we can safely remove this in one go.
