model-conversion : add support for SentenceTransformers (#16387)

* model-conversion : add support for SentenceTransformers

This commit adds support for models that use SentenceTransformer layers.

The motivation for this is that if converted model includes any of the
numbered layers specified in the original models repository then these
changes enable these models to be used and verified. Currently the
model-conversion only support the base model output without any of
the additional transformation layers.

Usage:
Convert the model that also includes the SentenceTransformer layers:
```console
(venv) $ export EMBEDDING_MODEL_PATH="~/google/embeddinggemma-300M"
(venv) make embedding-convert-model
```

Verify the produced embeddings from the converted model against the
original model embeddings:
```console
(venv) make embedding-verify-logits-st
```

The original model can be run using SentenceTransformer:
```console
(venv) make embedding-run-original-model-st
```

Run the converted model using "SentenceTransformer" layers whic
enables pooling and normalization:
```console
(venv) make embedding-run-converted-model-st
```

* add model-conversion example requirements

* add support for -st flag in embedding model conversion

This commit add support for the -st flag in the embedding model
conversion script. This will enable models to be converted using
sentence transformers dense layers.

* Disable test-thread-safety on s390x

In this test a model is downloaded,
then immediately loaded to check if more downloads are needed,
and then used for test.

There is no clean way to separate all those steps
 to add byteswapping between them, so just skip this test.
