Subject: servicemanager: vintf declared API

servicemanager already has to parse VINTF configurations, so exposing
this functionality here (mirroring hwservicemanager).

Note, this API, like isDeclared is not branded as "VINTF" for future
compatibility with APEX or other interfaces.

Bug: 168715768
Test: manual
