KVM: SEV: Update KVM_AMD_SEV Kconfig entry and mention SEV-SNP

SEV-SNP support is present since commit 1dfe571c12cf ("KVM: SEV: Add
initial SEV-SNP support") but Kconfig entry wasn't updated and still
mentions SEV and SEV-ES only. Add SEV-SNP there and, while on it, expand
'SEV' in the description as 'Encrypted VMs' is not what 'SEV' stands for.

No functional change.
