Add shared periodic cleanup function for AP mode

This new mechanism can be used to combine multiple periodic AP
(including P2P GO) task into a single eloop timeout to minimize number
of wakeups for the process. hostapd gets its own periodic caller and
wpa_supplicant uses the previously added timer to trigger these calls.
