In 32 bit SBL, when PCI PMEM64 exists, the OsLoader will hang
during boot in CreateIdentityMappingPageTables(). The function
is inteneded to be used in X64 mode only, and cannot handle
32bit well. So OsLoader should not call it for 32 bit build.
This patch also zeroed the allcated memory to ensure the unused
entries are all 0.

Current Execute32BitCode() passes in 64bit arguments into stack.
It should use 32bit arguments instead according to 32bit calling
convention. This patch fixed this issue.

SBL support to load PreOS and normal OS in a single boot option.
This patch tries to standardize the PreOS support.
The PreOS could be TrustyOS, PreOsChecker or others.
As long as PreOS flag is set in boot option, SBL will load and
boot PreOS before normal OS. If the preOS has specific requirement,
it could be addressed using PreOS image type.

BGRT can be used by bootloader to pass logo to OS. But BGRT can
only support 24bit or 32bit BMP format. If the bootloader uses
other bit format or indexed color format, the image has to be
converted before passing it to BGRT. This patch added support
to convert other BMP image format into 32bit format required by
BGRT.
This has been tested with Windows on Leafhill board. The SBL
logo was dispalyed properly while booting Windows.

As per TCG spec, if a Tpm2Startup(TPM_SU_STATE) fails during
S3 resume, a host reset should be done.
When BootGuard is enabled, ACM will notify of this failure via Bit46 in
BootGuardBootStatus register.

Since the EXT library we have in OS Loader
supports 2, 3, and 4 it will help to reduce
confusion for users who have noticed that
only 2 and 3 are currently printed.

For UEFI Linux boot, a new parameter was added into BOOT_PARAMS.
This patch added this parameter support so that ACPI base can
be passed directly to kernel.

Since SBL could be built into either x86 or x64 mode, and the payload
can also be x86 or x64 mode. When mixed modes are used, it is required
to switch to proper mode first before calling into payload entrypoint.
This patch added this check to switch to required mode before calling
into payload entry point.

During X64 enabling, there was a pending task to enable 32bit
MultiBoot support. It is not implemented. This patch added the
support to allow X64 SBL to boot a 32bit MB image through thunking.
As part of this patch, the ThunkLib is separated from the FspApiLib
so that it can be shared by other component.

Currently SBL library has GetDeviceAddr() to get the device
address based on device type and instance. This patch adds
SetDeviceAddr() to update a given device type and address so
that platform could update the device table dynamically.

This patch added new DrawFrameBuffer interface. It will draw the
framebuffer from a VGA like text buffer. Payload can use this
