Subject: [PATCH] Support the mdoc component name format.

Since the mdoc provider doesn't need to register a CredMan service and
can solely rely on the registration api, its component format will be
"packagename/packagename".

Bug: 274007049
Test: local deployment
Change-Id: I3dcf44eb4e6ffd4dca9d8f0a38395abe9bcf2fd0
