Setting FDBNetworkOption::FDB_NET_OPTION_TLS_KEY_BYTES has no effect

Hi!

For some reason setting `FDBNetworkOption::FDB_NET_OPTION_TLS_KEY_BYTES` and similar `TLS_CERT_BYTES`, `TLS_CA_BYTES` seems like does not have any effect. We use `fdb_network_set_option()` for this matter.

After setting everything we receive transaction timeouts and the following in client logs:
```

```
On the other hand setting environment variables `FDB_TLS_CERTIFICATE_FILE`, `FDB_TLS_KEY_FILE`, `FDB_TLS_CA_FILE` with the paths to the files with same content does the trick and everything works.

We've also tried setting `FDBNetworkOption::FDB_NET_OPTION_TLS_KEY_PATH` and other `_PATH` options with no effect as well.

Environment:
- FDB 7.1.51
- Client in Docker container `Linux c31802bb42bc 6.5.0-17-generic #17-Ubuntu SMP PREEMPT_DYNAMIC Thu Jan 11 14:01:59 UTC 2024 x86_64 x86_64 x86_64 GNU/Linux`

Start at the fdb_network_set_option() entry point and compare the byte and path options with the environment-variable configuration, using the reported TLS certificate verification failure as the symptom to reproduce. Done means the in-memory byte and path options establish the same successful TLS connection as the corresponding FDB_TLS_* files.
