Support SEV-SNP on GCP (#3011)
* terraform: enable creation of SEV-SNP VMs on GCP

* variant: add SEV-SNP attestation variant

* config: add SEV-SNP config options for GCP

* measurements: add GCP SEV-SNP measurements

* gcp: separate package for SEV-ES

* attestation: add GCP SEV-SNP attestation logic

* gcp: factor out common logic

* choose: add GCP SEV-SNP

* cli: add TF variable passthrough for GCP SEV-SNP variables

* cli: support GCP SEV-SNP for `constellation verify`

* Adjust usage of GCP SEV-SNP throughout codebase

* ci: add GCP SEV-SNP

* terraform-provider: support GCP SEV-SNP

* docs: add GCP SEV-SNP reference

* linter fixes

* gcp: only run test with TPM simulator

* gcp: remove nonsense test

* Update cli/internal/cmd/verify.go

* Update docs/docs/overview/clouds.md

Co-authored-by: Daniel Weiße <66256922+daniel-weisse@users.noreply.github.com>

* Update terraform-provider-constellation/internal/provider/attestation_data_source_test.go

Co-authored-by: Adrian Stobbe <stobbe.adrian@gmail.com>

* linter fixes

* terraform_provider: correctly pass down CC technology

* config: mark attestationconfigapi as unimplemented

* gcp: fix comments and typos

* snp: use nonce and PK hash in SNP report

* snp: ensure we never use ARK supplied by Issuer (#3025)

* Make sure SNP ARK is always loaded from config, or fetched from AMD KDS
* GCP: Set validator `reportData` correctly
