apps/btshell: Add parse_arg_addr to parse BLE address

We already have parse_arg_mac which parses MAC address, but new API
allows to include ":p" or ":r" ("-p"/"-r") at the end of address string
which indicates address type. This can speed up typing commands since
there is no need to enter long parameters with address type separately.
