  by returning errors if any of them is invoked out of order.

-Merges the addition of extended caps IE for assoc req, probe resp
 and beacons in a single place. This ensures that there are no
 duplicate Extended Caps IE in the frame. Moves the capability
 indication for BTM and HT20/40 from supplicant to wifi libs.

-Fix issue with frequent disconections when scanning for only a single
 channel.

-Prints error message and returns ESP_ERR_NOT_SUPPORTED in case
 esp32c2 tries to set bandwidth to HT40.

1885379ae3 esp_dpp: Fix retry with esp_supp_dpp_start_listen after failure
This fixes a subtle bug in which ESP_ERR_DPP_TX_FAILURE errors would
call esp_supp_dpp_stop_listen which sets the s_dpp_stop_listening flag
to true.  Subsequent attempts to restart listening with
esp_supp_dpp_start_listen then only attempt to listen once more for
500ms before reading the s_dpp_stop_listening flag again and giving up.

This contributes greatly to #10615, but the fix here is still largely
a work-around as it sometimes requires manually retrying a couple times
before it works.  Without this fix, any number of retries by
deinit/init again will seemingly not work as the retries for currently
unknown reasons.
