Shuo A Liu d4aaf99d86 hv: keylocker: Support keylocker backup MSRs for Guest VM 
The logical processor scoped IWKey can be copied to or from a
platform-scope storage copy called IWKeyBackup. Copying IWKey to
IWKeyBackup is called ‘backing up IWKey’ and copying from IWKeyBackup to
IWKey is called ‘restoring IWKey’.

IWKeyBackup and the path between it and IWKey are protected against
software and simple hardware attacks. This means that IWKeyBackup can be
used to distribute an IWKey within the logical processors in a platform
in a protected manner.

Linux keylocker implementation uses this feature, so they are
introduced by this patch.
