Bluetooth: Host: More specific printing of address type

[koffes]

Is your enhancement proposal related to a problem? Please describe.

No problem, but when calling

zephyr/include/zephyr/bluetooth/addr.h

Lines 242 to 243 in 3d2059f

	static inline int bt_addr_le_to_str(const bt_addr_le_t *addr, char *str,
	size_t len)

it may only print "random".

Describe the solution you'd like

The above is fine, and correct, but it would be nice if this could also account for the address being random static or random private. It may be as simple as looking at if CONFIG_BT_PRIVACY is set or not, but that needs to be checked.
