meta-speech-framework: enable building Alexa voiceagent against zeus

Changes:
- Tweak LAYERSERIES_COMPAT variable for alexa-auto-sdk's meta-aac
  layer to append zeus, since it's unclear when Amazon will get around
  to a new release that adds zeus support and it's straightforward to
  get it to build against zeus.
- Add BBMASK for nghttp2 recipe in meta-aac to avoid overlaying the
  one for the same version now available in meta-networking. This
  avoids rebuilding a bunch of dependencies when reconfiguring to
  enable agl-voiceagent-alexa.
- Add bbappend for avs-device-sdk to add a patch to disable -Werror
  for new g++ 9 "deprecated-copy" warning in the packaged copy of
  googletest, which avoids a build failure.

+Enable building with g++ 9.x
+
+Disable -Werror for new warning "deprecated-copy" to avoid build
+failure in the packaged copy of googletest with g++ 9.x.  This is
+hopefully temporary until googletest is upgraded or it becomes
+straightforward to build against an externally provided copy.
