<feature>[kvm]: support TPM revert without KMS

Support TPM snapshot group revert when ALLOWED_TPM_VM_WITHOUT_KMS
config is enabled. Skip key provider resolution to allow TPM
recovery without KMS dependency.

Changes:
- Add ALLOWED_TPM_VM_WITHOUT_KMS config check
- Skip key provider resolution when config is true
