The existing coverage fuzzing computed prop was unfortunately
implemented incorrectly, since it wasn't checking the `length` property
of the array, so it _always_ returned true.

Encapsulating the logic in a method ensures it's done consistently
across report types.

This change was first made
in https://gitlab.com/gitlab-org/gitlab/-/merge_requests/40088 when
I needed to add a policy for another service. Noting that the
prometheus service thus became redundant, it is removed.

It seems the first usage of this class was in
https://gitlab.com/gitlab-org/gitlab/commit/edeab72399a42259666948434d660f7acff3a3d7,
but even then, the class wasn't defined in CSS, and as far as I can
tell, never has been.
