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.

Bug-AGL: SPEC-2765

+Remove copying of library dependencies
+
+Since we are targeting building into an image, the widget build does
+not have to copy host library dependencies into the widget as it would
+when being built standalone with the SDK.  Remove the copying, as
+runtime dependencies will be used to pull the libraries in.
