OPP: Migrate set-prop-name helper API to use set-config helpers

Now that we have a central API to handle all OPP table configurations,
migrate the set-prop-name family of helpers to use the new
infrastructure.

The return type and parameter to the APIs change a bit due to this,
update the current users as well in the same commit in order to avoid
breaking builds.
