Zide Chen 2bd269c11c hv: nested: support for VMCLEAR emulation 
This patch is to emulate VMCLEAR instruction.

L1 hypervisor issues VMCLEAR on a VMCS12 whose state could be any of
these: active and current, active but not current, not yet VMPTRLDed.

To emulate the VMCLEAR instruction, ACRN sets the VMCS12 launch state to
"clear", and if L0 already cached this VMCS12, need to sync it back to
guest memory:

- sync shadow fields from shadow VMCS VMCS to cache VMCS12
- copy cache VMCS12 to L1 guest memory

Tracked-On: #5923
