meta-app-framework: Update app template scheme

Changes to support the move to systemd unit based app enumeration in
applaunchd:
- Bump applaunchd SRCREV to pick up enumeration changes.
- Tweak the polkit rule to match agl-app* instead of agl-app@*
  to allow more flexibility with respect to different app templates.
- Tweak the Description field definition in the agl-app service
  template to just use the instance name, as that field is now used
  for the application display name by applaunchd.
- Add a agl-app-web service template for web apps.
- Add a agl-app.bbclass for use in application recipes to simplify
  installation of the now required systemd template instances and
  potential generation of override files to tweak application
  configuration.
- Split the agl-app and agl-app-web templates into their own packages
  in the applaunchd recipe so they can be depended on by applications
  as required.
- Move applaunchd installed systemd units and override files to
  /lib/systemd/system since that matches the upstream recommendation
  for units installed as part of the system installation.
