For WPA3 connection nearing PMK lifetime expiry, PMK Cache
needs a re-authentication or the cache will expire. After
current expiry of 12 hours Station ends up sending a deauth
to the AP. An SAE re-authentication also cannot occur without
a disconnection with current implementation. So increase the
PMK lifetime to 100 days for now.
1) Added PMK caching module from wpa_supplicant.
2) Modified wpa_sm to
a) Add entry to PMK cache when first time associated to an AP.
b) Maintain entry across the associations.
c) Clear current PMKSA when deauth happens.
d) Search for an entry when re-associating to the same AP and
set it as current PMKSA
e) Wait for msg 1/4 from AP instead of starting EAP authentication.
f) Check PMKID in msg 1 with current PMKSA/cache.
g) Use the cached PMK to complete 4-way handshake.
3) Remove config_bss callback as it was redundant and used to cause
problems for PMK caching flow.
Closes IDF-969
