Fix several issues with the CDM association dialog:

Affecting only self-managed associations.

Dialog title and summary:

 - Fix the app name resource in self-managed profiles titles and
   summaries. The resources are defined correctly, they expect the
   app name to be passed, but the substitution is actually done with
   the device name, which is wrong. Also, add the device name to the
   title and summary string resources to make the message

Helper dialog:

 - The helper title is hardcoded "Cross-Device Services". It needs
   to be the name of the app requesting the association.

 - Remove the now obsolete helper title string resources.

 - Make the message of APP_STREAMING profile consistent with the one
   for NEARBY_DEVICE_STREAMING

 - Add a map of profile to helper summary, similarly to the rest of
   the CDM resources.

Clean up:

 - Clean up launched VDM flag interactiveScreenMirror. It's low-risk,
   has no API changes and has been in Nextfood for months.

 - Remove the now obsolete string resources after the mirroring flag
   is cleaned up.

 - Remove the unused permission constants, string and drawable
   resources for APP_STREAMING and NEARBY_DEVICE_STREAMING profiles.
   They are obsolete after the mirroring flag is cleaned up because
   there are no "permissions" associated with these profiles.
