Bug fix for SAP in 6G/WPA3_SAE mode

To enable SAP properly at 6G:
1) enable 11AX compilation flag if WIFI_FEATURE_HOSTAPD_11AX is set
(will be set on a per device basis)
2) set sae_pwe = 1 (hash-to-element only) for 6G band only mode and
sae_pwe = 2 for other modes (both hunting-and-pecking loop and
hash-to-element enabled) when WPA3_SAE mode is enabled

Bug: 168348861
Test: manual test with SAP and clients in 6G/WPA3_SAE mode, 5G/OPEN, 5G/WPA2, 5G/WPA3_SAE modes.
