This patch series provides support for running EDK2/OVMF under SEV-ES.

Secure Encrypted Virtualization - Encrypted State (SEV-ES) expands on the
SEV support to protect the guest register state from the hypervisor. See
"AMD64 Architecture Programmer's Manual Volume 2: System Programming",
section "15.35 Encrypted State (SEV-ES)" [1].

In order to allow a hypervisor to perform functions on behalf of a guest,
there is architectural support for notifying a guest's operating system
when certain types of VMEXITs are about to occur. This allows the guest to
selectively share information with the hypervisor to satisfy the requested
function. The notification is performed using a new exception, the VMM
Communication exception (#VC). The information is shared through the
Guest-Hypervisor Communication Block (GHCB) using the VMGEXIT instruction.
The GHCB format and the protocol for using it is documented in "SEV-ES
Guest-Hypervisor Communication Block Standardization" [2].

The main areas of the EDK2 code that are updated to support SEV-ES are
around the exception handling support and the AP boot support.

Exception support is required starting in Sec, continuing through Pei
and into Dxe in order to handle #VC exceptions that are generated.  Each
AP requires it's own GHCB page as well as a page to hold values specific
to that AP.

AP booting poses some interesting challenges. The INIT-SIPI-SIPI sequence
is typically used to boot the APs. However, the hypervisor is not allowed
to update the guest registers. The GHCB document [2] talks about how SMP
booting under SEV-ES is performed.

Since the GHCB page must be a shared (unencrypted) page, the processor
must be running in long mode in order for the guest and hypervisor to
communicate with each other. As a result, SEV-ES is only supported under
the X64 architecture.

Changes since v7:
- Reserve the SEV-ES workarea when S3 is enabled
- Fix warnings issued by the Visual Studio compiler
- Create a NULL VmgExitLib instance that is used for VMGEXIT
  related operations as well as #VC handling. Then create the full
  VmgExitLib support only in OvmfPkg - where it will be used. This
  removes a bunch of implementation code from platforms that will
  not be using the functionality.
- Remove single use interfaces from the VmgExitLib (VmgMmioWrite
  and VmgSetApJumpTable)

Changes since v6:
- Add function comments to all functions, including local functions
- Add function parameter direction to all functions (in/out)
- Add support for MMIO MOVZX/MOVSX instructions
- Ensure the per-CPU variable page remains encrypted
- Coding-style fixes as identified by Ecc

Changes since v5:
- Remove extraneous VmgExitLib usage
- Miscellaneous changes to address feedback (coding style, etc.)

Changes since v4:
- Move the SEV-ES protocol negotiation out of the SEC exception handler
  and into the SecMain.c file. As a result:
  - Move the SecGhcb related PCDs out of UefiCpuPkg and into OvmfPkg
  - Combine SecAMDSevVcHandler.c and PeiDxeAMDSevVcHandler.c into a
    single AMDSevVcHandler.c
- Consolidate VmgExitLib usage into common LibraryClasses sections
- Add documentation comments to the VmgExitLib functions

Changes since v3:
- Remove the need for the MP library finalization routine. The AP
  jump table address will be held by the hypervisor rather than
  communicated via the GHCB MSR. This removes some fragility around
  the UEFI to OS transition.
- Rename the SEV-ES RIP reset area to SEV-ES workarea and use it to
  communicate the SEV-ES status, so that SEC CPU exception handling is
  only established for an SEV-ES guest.
- Fix SMM build breakageAdd around QemuFlashPtrWrite().
- Fix SMM build breakage by adding VC exception support the SMM CPU
  exception handling.
- Add memory fencing around the invocation of AsmVmgExit().
- Clarify comments around the SEV-ES AP reset RIP values and usage.
- Move some PCD definitions from MdeModulePkg to UefiCpuPkg.
- Remove the 16-bit code selector definition from MdeModulePkg

Changes since v2:
- Added a way to locate the SEV-ES fixed AP RIP address for starting
  AP's to avoid updating the actual flash image (build time location
  that is identified with a GUID value).
- Create a VmgExit library to replace static inline functions.
- Move some PCDs to the appropriate packages
- Add support for writing to QEMU flash under SEV-ES
- Add additional MMIO opcode support
- Cleaned up the GHCB MSR CPUID protocol support

Changes since v1:
- Patches reworked to be more specific to the component/area being updated
  and order of definition/usage
- Created a library for VMGEXIT-related functions to replace use of inline
  functions
- Allocation method for GDT changed from AllocatePool to AllocatePages
- Early caching only enabled for SEV-ES guests
- Ensure AP loop mode set to halt loop mode for SEV-ES guests
- Reserved SEC GHCB-related memory areas when S3 is enabled
