[RFC 12/34] wpa_supplicant: Add more NAN driver flags

[Andrei Otcheretianski]

Add new NAN driver flags to indicate support for:
  - Synchronization offload and support for additional NAN sync
    parameters.
  - Support for user space NAN DE implementation which requires the
    driver to send DW notification and be able to transmit and receive
    SDF frames over NAN device interface with the correct timing.
