Describe the bug:
Currently the config for LLaMA 3.2 3B is not using tied weights. Only the 1B model is currently supported (https://github.com/facebookresearch/fairseq2/blob/main/src/fairseq2/models/llama/_config.py#L257)

Describe how to reproduce:
Loaded LLaMA 3.2 3B and confirmed weights are tied

In [13]: (model.decoder_frontend.embed.weight == model.final_proj.weight).all()
Out[13]: tensor(True)
