attestation: add SNP-based attestation for aws-sev-snp (#1916)

Browse source 
* config: move AMD root key to global constant
* attestation: add SNP based attestation for aws
* Always enable SNP, regardless of attestation type.
* Make AWSNitroTPM default again

There exists a bug in AWS SNP implementation where sometimes
a host might not be able to produce valid SNP reports.
Since we have to wait for AWS to fix this we are merging SNP
attestation as opt-in feature.
