hostapd: Add support for OWE offload for STA/AP interface

Browse source 
The driver advertising OWE offload support would take care of
Diffie-Hellman Parameter element generation and processing part. The
driver would be responsible for OWE PMK generation in this case.

Avoid the Diffie-Hellman Parameter element handling in
wpa_supplicant/hostapd for drivers advertising OWE offload support. This
change is applicable only for drivers supporting 4-way handshake
offload.
