WPS strict disables workarounds with different APs and may cause
IOT issues. Remove this as default and introduce as a config option.
Also declare esp device as single band mobile device otherwise
WFA sniffer was not able to identify it in the certification setup.
Some APs incorrectly advertize newer WPS2.0 config method bits
without setting bits for the corresponding older methods. This
results in failures during 8-way handshake. Add a workaround to
relax this check so that WPS handshake can proceed.
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
