HCIHandler: Add support for HCI resolvable functions: add, del, clear, read.., set..

NOTE that the following seem not to be supported in Linux/BlueZ:
- LE_READ_PEER_RESOLV_ADDR
- LE_READ_LOCAL_RESOLV_ADDR

The others are coded within BlueZ,
but I received 0x01 UNKNOWN_COMMAND as a HCIStatusCode

Used kernel for analysis:
