* feat: Add comprehensive test cases for `VerifyWithCoRIM` including success and measurement mismatch, and refine reference value validation.

* feat: Add Azure and TDX attestation verification tests and abstract external service dependencies for improved testability.

Signed-off-by: Sammy Oina <sammyoina@gmail.com>

* feat: Add new test cases for Azure measurement extraction, EAT platform types, IGVM measurement stopping, vTPM CoRIM verification, and GCP OVMF download CLI.
