Implement robust caching (server)

Flag:
- Use flag to enable/disable robust caching on server side

btif_storage
- Add APIs to set/get/remove database hash and client supported features

Database Hash
- Add database hash definition into GATT profile
- Set client to change aware when reading database hash

Client Supported Features
- Add write check for client supported features characteristic
- Store client supported feature into btif_storage

Behaviors
- When a service is added/removed
  . Update database hash
  . Set clients that support robust caching to change unaware
- After ack for service changed indication is received
  . Set the client to change aware
- When the client is change unaware
  . Allow request of reading database hash (by handle or by uuid)
  . Allow write_execute, config_mtu and handle_value_conf
  . Send DATABASE_OUT_OF_SYNC error when it is a request
  . Ignore if it is a command
  . After the response is sent, set the client to change aware
- When a client is set from change unaware to change aware
  . Store current database hash to btif_stroage for that client

Connect and Disconnect:
- When a tGATT_TCB instance is allocated, load status from btif_storage
- When disconnected, if the device is untrusted, remove data from btif_storage
