ee1f8262b8 OvmfPkg: Call PlatformInitializeConsole for GPU passthrough case 
For GPU passthrough support we have to initialize the console after
EfiBootManagerDispatchDeferredImages() has loaded ROMs, so call it after
this. This was the calling order before the TCG physical presence support
had to be moved and the console initialized earlier so user interaction
could be supported before processing TCG physical presence opcodes.

b8675deaa8 OvmfPkg: Handle TPM 2 physical presence opcodes much earlier 
Handle the TPM 2 physical presence interface (PPI) opcodes in
PlatformBootManagerBeforeConsole() before the TPM 2 platform hierarchy
is disabled. Since the handling of the PPI opcodes may require inter-
action with the user, initialize the keyboard before handling PPI codes.

b261a30c90 OvmfPkg/AmdSev: add Grub Firmware Volume Package 
This is used to package up the grub bootloader into a firmware volume
where it can be executed as a shell like the UEFI Shell.  Grub itself
is built as a minimal entity into a Fv and then added as a boot
option.  By default the UEFI shell isn't built but for debugging
purposes it can be enabled and will then be presented as a boot option
(This should never be allowed for secure boot in an external data
centre but may be useful for local debugging).  Finally all other boot
options except grub and possibly the shell are stripped and the boot
timeout forced to 0 so the system will not enter a setup menu and will
only boot to grub.  This is done by copying the
Library/PlatformBootManagerLib into Library/PlatformBootManagerLibGrub
and then customizing it.

Boot failure is fatal to try to prevent secret theft.
