OvmfPkg: Add AMD SEV-ES DebugVirtualization feature support
The SEV-ES DebugVirtualization feature enables type B swapping of
debug registers on #VMEXIT and makes #DB and DR7 intercepts
unnecessary and unwanted.
When DebugVirtualization is enabled, this stops booting if
interaction from the HV.
Add new API to PEI, SEC, DXE.
This does not change the existing behaviour yet.
