vshl-capabilities:

This API is responsible for brokering capbilities related
messages from voiceagents to apps and vice versa.

Verbs exposed are

navigation/publish
navigation/subscribe
phonecontrol/publish
phonecontrol/subscribe
playbackcontroller/publish
playbackcontroller/subscribe
guiMetadata/publish
guiMetadata/subscribe

This API exposes publish and subscribe methods for all
the speech framework domains/capabilities. For eg. navigation,
phonecontrol etc. This API is used by apps and low level voice
agent binding to subscribe and publish these capability messages
whenever applicable.
This specific commit is for vshl-capabilities API.
