Feature Request: Add Support for AMD SEV-SNP

[kvinwang]

Following the merge of PR #437, dstack now supports a flexible attestation format designed for multi-platform compatibility. While our previous implementation was limited to Intel TDX, the new format paves the way for supporting other TEE technologies.

Implementation Guide

Here is a high-level implementation path outlined:

1. Update Attestation Data Structures

• In dstack-attest/src/attestation.rs, introduce a DstackAmdSevSnp variant to both the AttestationMode and AttestationQuote enums.

2. Implement Quote Logic

• Implement the quote generation and verification logic for the new DstackAmdSevSnp variant.
• Ensure this mirrors the logic currently used where AttestationMode::DstackTdx is referenced.

3. Configure VMM & QEMU

• In vmm/src/app/qemu.rs, Update dstack-vmm to handle QEMU launch arguments specific to AMD SEV-SNP.
• Add a platform configuration entry to vmm.toml to explicitly select the TEE backend, or implement platform auto-detection.
