Adding some flexibility to the program through optional parameters and
global define, so that other targets can use the generator.
* A global define is added so that we can choose at build time if we
want to use 32-bit or 64-bit base structures.
* A first optional parameter is added so the user can provide the
expected blob size of the generated binary.
* A second optional parameter is added so the user can specify an output
file to which the generated output will be printed.
The default behavior isn't modified.

In order to probe the SEV feature the BaseMemEncryptLib and Reset vector
reads the SEV_STATUS MSR. Cache the value on the first read in the
workarea. In the next patches the value saved in the workarea will
be used by the BaseMemEncryptLib. This not only eliminates the extra
MSR reads it also helps cleaning up the code in BaseMemEncryptLib.

The commit ade62c18f4 caused a boot failure
when OVMF is build with SECURE_BOOT/SMM enabled.
This happen because the above commit extended the BaseMemEncryptSevLib.inf
to include VmgExitLib. The FvbServicesSmm uses the functions provided
by the MemEncryptSevLib to clear the memory encryption mask from the
page table. It created a dependency, as shown below
OvmfPkg/FvbServicesSmm.inf
---> MemEncryptSevLib class
---> "OvmfPkg/BaseMemEncryptSevLib/DxeMemEncryptSevLib.inf" instance
---> VmgExitLib
---> "OvmfPkg/VmgExitLib" instance
---> LocalApicLib class
---> UefiCpuPkg/BaseXApicX2ApicLib/BaseXApicX2ApicLib.inf instance
---> TimerLib class
---> "OvmfPkg/AcpiTimerLib/DxeAcpiTimerLib.inf" instance
---> PciLib class
---> "OvmfPkg/DxePciLibI440FxQ35/DxePciLibI440FxQ35.inf" instance
The LocalApicLib provides a constructor, execution of the constructor
causes an exception. The SEV-ES and SEV-SNP do not support the SMM, so
skip including the VmgExitLib chain. Use the module override to use the
VmgExitLibNull to avoid the inclusion of unneeded LocalApicLib dependency
chain in FvbServicesSmm. We ran similar issue for AmdSevDxe driver,
see commit 19914edc5a
After the patch, the dependency look like this:
OvmfPkg/FvbServicesSmm.inf
---> MemEncryptSevLib class
---> "OvmfPkg/BaseMemEncryptSevLib/DxeMemEncryptSevLib.inf" instance
---> VmgExitLib
---> "UefiCpuPkg/Library/VmgExitLibNull" instance

It's a UINT8 (enum) PCD telling where the PcdVideoHorizontalResolution
and PcdVideoVerticalResolution values are coming from. It can be:
0 (unset aka default from dsc file), or
1 (from PlatformConfig), or
2 (set by Video Driver).
It will be used by video drivers to avoid overriding PlatformConfig
values, or override each others values in case multiple display devices
are present.
The underlying problem this tries to solve is that the GOP protocol has
no way to indicate the preferred video mode. On physical hardware this
isn't much of a problem because using the highest resolution available
works just fine as that is typically the native display resolution
But in a virtual machine you don't want come up with a huge 4k window by
default just because the virtual vga is able to handle that. Cutting
down the video mode list isn't a great solution either as that would
also remove the modes from the platform configuration so the user
wouldn't be able to pick a resolution higher than the default any more.
So with patch drivers can use use PcdVideoHorizontalResolution and
PcdVideoVerticalResolution to indicate what the preferred display
resolution is, without overwriting the user preferences from
PlatformConfig if present.
A possible alternative approach would be to extend the GOP protocol, but
I'm not sure this is a good plan given this is mostly a problem for
virtual machines and using PCDs allows to keep this local to OvmfPkg.
