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 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
