Add the needed infrastructure for the Extended Key ID tests, update
tests overriding RSN Capabilities to work with and without Extended Key
ID support and add additional interoperability tests for Extended Key
ID.
When supported by the platform (hwsim) all tests will use Extended Key
ID by default while still being able to run all tests not directly linked
to Extended Key ID.
Signed-off-by: Alexander Wetzel <alexander@xxxxxxxxxxxxxx>

There is of course more we could test here. But all new corner cases
should be covered and while especially wlantest could get more attention
it's working fine as it is.
Sample test runs are linked in the cover letter of the series.
