btaa: HCI command process

Introduce the first phase of BTAA HCI command process. Upon receives a
HCI command packet, processing module will search the opcode against a
lookup table, only simple (contains only device info) and identifiable
command will be processed. Pair information of connection handle and
device address are associated and recorded for future references.

The lookup table is a skelton implementation that does not contain 100%
correct information.
