Add SpeziLLMFog that performs dynamic LLM job dispatch to fog nodes

♻️ Current situation & Problem

Currently, SpeziLLM doesn't support a privacy friendly execution of LLM inference jobs within the local network.

⚙️ Release Notes

• Add SpeziLLMFog that performs dynamic LLM job dispatch to fog nodes.
• Include a FogNode component that easily starts up a complete fog node ready to perform LLM inference requests via docker compose.
• Introduce custom LLMContext type that holds the internal state of the LLMSession, instead of relying on the SpeziChat models.

📚 Documentation

Added proper readmes, docs, and in-line comments

✅ Testing

Manual testing (for now)

@PSchmiedmayer The Markdown link check is supposed to fail, as I'm already using SPM docs that are published as soon as this PR is merged.

@PSchmiedmayer Please adjust the merge checks of the repo, as I added additional testing jobs for iPad, Vision, and macOS

[PSchmiedmayer]

Thank you for all the work that went into this @philippzagar; greatly appreciated!

It looks great, happy to see this merged and completing the major LLM features we wanted to implement 🚀

[philippzagar]

@PSchmiedmayer Please merge the PR, the failure of the markdown check is intended as I'm already referencing soon-to-be-published SPI docs in the README etc. :)
Also, please adjust the merge checks of the repo as I adjusted the CI jobs to build on all supported platforms in DEBUG and RELEASE mode

[PSchmiedmayer]

Thank you @philippzagar for the PR and all the advancements! Thanks for adding all the additional automated tests! 🚀
