meta-speech-framework: Update Alexa Auto SDK to v2.3

Changes:
- Mask out the duplicate libopus recipe, the same version is available
  from a recipe in meta-oe.
- Update BBFILES addition for the audio module in the feature template
  to work with yet another new audio output backend.
- Update the AlexaAutoCoreEngineConfig.json.in template based on the
  new sample JSON in 2.3.
- Update alexa-voiceagent-config recipe to add new configuration
  variables ALEXA_LOCALE, ALEXA_TIMEZONE, ALEXA_MFG_NAME, and
  ALEXA_DESCRIPTION to match requirements of the updated configuration
  JSON.
- Remove local alexa-voiceagent-service patches merged by Amazon, and
  update 0001-remove-library-dependency-copying.patch for 2.3.
- Update SDK module DEPENDS for alexa-voiceagent-service recipe to match
  what seems required now with 2.3.
- Remove avs-device-sdk patch for building with g++ 9.x, as it is no
  longer required.
- Add avs-device-sdk patch to workaround hang seen on first connection.
- Add bbappends for aac-module-car-control and aac-module-messaging
  recipes to fix their nlohmann-json DEPENDS to work with the recipe
  that is available in meta-oe.
- Rework aac-module-system-audio.bbappend to enable the PipeWire support
  that has been merged into the module.
