x86/sev: Detect/setup SEV/SME features earlier in boot

Browse source

sme_enable() handles feature detection for both SEV and SME. Future
patches will also use it for SEV-SNP feature detection/setup, which
will need to be done immediately after the first #VC handler is set up.
Move it now in preparation.
