- build quictls with `no-deprecated` in CI to have test coverage for
this OpenSSL 3 configuration.
- don't call `OpenSSL_add_all_algorithms()`, `OpenSSL_add_all_digests()`.
The caller code is meant for OpenSSL 3, while these two functions were
only necessary before OpenSSL 1.1.0. They are missing from OpenSSL 3
if built with option `no-deprecated`, causing build errors:
```
vtls/openssl.c:4097:3: error: call to undeclared function 'OpenSSL_add_all_algorithms'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
vtls/openssl.c:4098:3: error: call to undeclared function 'OpenSSL_add_all_digests'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
```

Regression from b6e6d4ff8f #12030
Bug: https://github.com/curl/curl/issues/12380#issuecomment-1822944669
Reviewed-by: Alex Bozarth
- vquic/curl_ngtcp2: fix using `SSL_get_peer_certificate` with
`no-deprecated` quictls 3 builds.
Do it by moving an existing solution for this from `vtls/openssl.c`
to `vtls/openssl.h` and adjusting caller code.
```
vquic/curl_ngtcp2.c:1950:19: error: implicit declaration of function 'SSL_get_peer_certificate'; did you mean 'SSL_get1_peer_certificate'? [-Wimplicit-function-declaration]
```
Ref: https://github.com/curl/curl/actions/runs/6960723097/job/18940818625#step:24:1178
- curl_ntlm_core: fix `-Wunused-parameter`, `-Wunused-variable` and
`-Wunused-function` when trying to build curl with NTLM enabled but
without the necessary TLS backend (with DES) support.
