mesh: Add support for PMKSA caching
This patch add functionality of mesh SAE PMKSA caching. If the local STA already has peer's PMKSA entry in the cache, skip SAE authentication and start AMPE with the cached value. If the peer does not support PMKSA caching or does not have the local STA's PMKSA entry in the cache, AMPE will fail and the PMKSA cache entry of the peer will be removed. Then STA retries with ordinary SAE authentication. If the peer does not support PMKSA caching and the local STA uses no_auto_peer=1, the local STA can not retry SAE authentication because NEW_PEER_CANDIDATE event cannot start SAE authentication when no_auto_peer=1. So this patch extends MESH_PEER_ADD command to use duration(sec). Throughout the duration, the local STA can start SAE authentication triggered by NEW_PEER_CANDIDATE even though no_auto_peer=1. This commit requires commit 70c93963edefa37ef84b73efb9d04ea10268341c ('SAE: Fix PMKID calculation for PMKSA cache'). Without that commit, chosen PMK comparison will fail.
