Add agl-voiceagent-alexa feature
Add feature and associated recipes and bbappends to enable building
the Amazon Alexa voice agent for the speech framework using the Alexa
Automotive SDK 2.0 release. A separate feature is used to accomodate
potentially building with a different voiceagent provider.
Some follow on development is required to add PipeWire support to the
new gstreamer extension added in AAC 2.0, see SPEC-2767.
