UefiCpuPkg: Implement library support for VMGEXIT
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=2198
To support handling #VC exceptions and issuing VMGEXIT instructions,
create a library with functions that can be used to perform these
#VC/VMGEXIT related operations. This includes functions for:
- Handling #VC exceptions
- Preparing for and issuing a VMGEXIT
- Performing MMIO-related write operations to support flash emulation
- Performing AP related boot opeations
The base functions in this driver will not do anything and will return
an error if a return value is required. It is expected that other packages
(like OvmfPkg) will create a version of the library to fully support an
SEV-ES guest.
