AP MLD: Add link details in STATUS command

Include link ID and partner link details in the STATUS command output
for AP MLDs.

The details would be seen as below for an AP MLD interface:

$ hostapd_cli -i wlan0 status | grep link
num_links=1
link_id=0
link_addr=AA:BB:CC:DD:EE:FF

$ hostapd_cli -i wlan1 status | grep link
num_links=2
link_id=0
link_addr=AA:BB:CC:DD:EE:FF
partner_link[1]=AA:BB:CC:DD:EE:AA
