COCOS-525-487 - Refactor attestation and atls (#562)

Browse Source 
* Refactor attestation handling to remove quoteprovider dependency

- Removed references to quoteprovider in various files, replacing them with vtpm where necessary.
- Updated function signatures and implementations to use SEVNonce instead of quoteprovider.Nonce.
- Introduced new vtpm package to handle SEV-related attestation logic, including fetching and verifying attestation reports.
- Adjusted tests to reflect changes in the attestation logic and ensure compatibility with the new structure.
- Deleted the now redundant quoteprovider/sev_test.go file.
