feat(types)!: delete Turin fallback and change TCB class

[hyperfinitism]

This pull request refines the processing of processor models within the pysnputils.types module, ensuring the codebase remains compatible should processors beyond the Turin model be introduced.

What's changed

• Remove Turin auto-detection fallback: drop the fallback path for Turin + V2 report
• Update TcbVersion model handling: replace the turin boolean flag with a processor_model field so the model-specific logic scales beyond Turin.
