wifi: nl80211: permit userspace to pass supported selectors

Browse Source 
Currently the SAE_H2E selector already exists, which needs to be
implemented by the SME. As new such selectors might be added in the
future, add a feature to permit userspace to report a selector as
supported.

If not given, the kernel should assume that userspace does support
SAE_H2E.
