[nrf fromtree] Bluetooth: Host: Validate periodic advertising report length - #4496

…bricated responses

The fake controller responds to LE Set Extended Scan Parameters, LE Set
Extended Scan Enable and Reset with Command Complete events that carry
no return parameters, although these commands return a status. The host
has been reading the status from beyond the fabricated event parameters,
which happened to yield success. Add the status return parameter, like
the other status-only commands in the table already have, in preparation
for the host validating command responses against the event length.

…riodic report test

Enable periodic advertising sync in the test configuration and add a
test which establishes a sync with the fake controller and sends
periodic advertising reports whose length field claims more data than
the event carries. The reports must be dropped without invoking the
receive callback, and the sync must remain usable afterwards.
