Add chip_crypto=boringssl flag

[leonm1]

Fixes #24.

boringssl is bundled as part of the repo and built and statically linked into the resulting library, so it should always be linked to the version used by all other matter SDK users.

I think this solution is much preferrable to running EoL openssl.

• I verified this builds on github actions for x86_64 and Mac (I don't have an aarch64 runner to test on).
• I used the built wheels as inputs to python-matter-server on linux x86_64, booted it up, and it works

This seems like a good approach, especially since from what i know Google uses boringssl as well. It is probably much more likely that use of this library is well maintained.

Thanks! 🙏
