fix(esp_wifi): Add support for WPA3 + WPA3_EXT_PSK mixed mode and minor bugfixes

- Add support for WPA3 + WPA3_EXT_PSK mixed mode
- Improvements in scan and connect path as per specifications along with
  minor bugfixes
- When AP advertises all PSK modes (WPA, WPA2 and WPA3), make sure that
  station treats it as WPA2_WPA3_PSK mixed mode.
