Bluetooth: Tests: Remove usage of auto name in AD

The advertiser options to automatically add the name in the scan
response and the advertising data will be deprecated.

Update the tests that were relying on those options. A lot of test were
actually not using the name, for those the name have simply been
removed. For the others that were using the name, add it in the
advertising data or the scan response data.
