Adds a mechanism to delete CPA values for a given user (#30330)

* Adds a mechanism to delete CPA values for a given user

This requires improving the Property Value service to enable delete
all values for a given target, so a new method was created that allows
to delete filtering by targetType and targetID (required) and
optionally for a specific groupID in case the caller wants to affect
all values for a target (useful in case you remove a post for example
and want to delete all values pointing to that post regardless of the
feature they belong to) or only those that belong to a specific
feature.

* Fix property value tests

* Fix after merge and update method name

* Fix linter
