Rework PulseAudio / audiomanager config setup to allow over-rides

Changes include:
- Move from having PulseAudio configuration changes in the recipe
  bbappend as patches to using the .include directive in default.pa
  to pick up configuration fragments provided by other recipes.
- Use virtual/pulseaudio-config to pick up the previously hard-coded
  configuration for enabling module-router.so, which is now provided
  by a new recipe that sets RPROVIDES appropriately.  This allows
  over-riding the desired configuration if needed.
- Switch the audiomanager-plugins-config dependency to using
  virtual/audiomanager-plugins-config so that it can be over-ridden
  with PREFERRED_PROVIDER if needed.

Bug-AGL: SPEC-1025, SPEC-1026, SPEC-1027

-Subject: [PATCH] disable module-role-cork by default
-
-module-role-cork's hardcoded default corking policies can conflict
-with module-router and AudioManager's configurable routing policies.
-Disable it to avoid unwanted corking changes on streams.
