Make ports for LDAP analyzers fully configurable

This moves the ports the LDAP analyzers should be triggered on from the
EVT file to the Zeek module. This gives users full control over which
ports the analyzers are registered for while previously they could only
register them for additional ports (there is no Zeek script equivalent
of `Manager::UnregisterAnalyzerForPort`).

The analyzers could still be triggered via DPD, but this is intentional.
To fully disable analyzers users can use e.g.,

```zeek
event zeek_init()
    {
    Analyzer::disable_analyzer(Analyzer::ANALYZER_LDAP_TCP);
    }
```
