EAP reauth frames are dropped at various stages due to current
implementation of WPA2 ENT states and EAP SM init/deinit logic.
Route EAPOL frames based on EAP pkt type and maintain EAP SM
to facilitate EAP re-authentication process.
The full fix for the change includes a fix from wifi library
(commit - 36f99df849214fbf9b0d15e58554632a568e05aa).
Move supplicant to idf and do following refactoring:
1. Make the folder structure consitent with supplicant upstream
2. Remove duplicated header files and minimize the public header files
3. Refactor for WiFi/supplicant interfaces
