Support translation models #1113

Problem Description

As it stands for now, we do not support any text translation models in our package. Having them could be useful in many contexts.

What should be done

Explore available translation models and try to export them to ExecuTorch format. A good candidate to begin with is Tencent Hunyuan Translation Model.

Benefits to React Native ExecuTorch

Translation models could be very useful on it's own, as well as in integration with other language models. Natural candidates for such synergy are LLMs or the upcoming multilingual text-to-speech (#712).

One idea to utilizes such models would be a fully-offline voice translation app, allowing a complete verbal communication in different languages using S2T, T2S and translation model running between these layers.
