Improve Javadoc of slice test annotations

This commit harmonizes the phrasing that we use to describe what
components are considered for scanning when a slice test is enabled.

This makes the description of the default filter explicit, with an
exhaustive description of the annotations and/or base classes.

Closes gh-41914
