Offload HAL Service: Send messages to CHRE

Browse Source 
The following messages are to be sent to the nano app in response to
invocation of the Offload HAL APIs from the client

CHRE interface will send the following commands to context hub
- Get hub info and nano app list requests
The callbacks from the socket will handle responses to these requests
