… Ubuntu 24.04 (#15005)

fixes #15004

Co-authored-by: Paolo Greppi <paolo.greppi@libpf.com>

This commit adds support for the 18-layer model type in the Gemma3
series, which is the size of the Gemma3-270m model.

The motivation for this commit is was the only change required for
Gemma3-270m to be converted to GGUF format and used with llama.cpp.

Once the model has been converted and uploaded to Huggingface it can be
used like this:
```console
$ ./build/bin/llama-cli -hf ggml-org/gemma-3-270m-GGUF:Q8_0
```

* eval-callback : stop on first NaN

* cont : log error

* test-opt: fix backend support check

* Update tests/test-opt.cpp
