Add Candle ML framework example

[dimakuv]

Candle is a minimalist ML framework for Rust with a focus on performance and ease of use. This commit adds two examples with Candle: simple matrix multiplication (to quickly test functionality) and Quantized LLaMA (to test performance).

Originally was submitted in core Gramine repo, but it was agreed to move it in this separate repo: gramineproject/gramine#1938

No, I think we should add the loader.entrypoint now, and then apply #99 to all examples, including Candle.
