x86: vMCE save and restore
This patch provides vMCE save/restore when migration.
1. MCG_CAP is well-defined. However, considering future cap extension,
we keep save/restore logic that Jan implement at c/s 24887;
2. MCi_CTL2 initialized by guestos when booting, so need save/restore
otherwise guest would surprise;
3. Other MSRs do not need save/restore since they are either error-
related and pointless to save/restore, or, unified among all vMCE
platform;
