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.

This introduces a new PCD 'PcdPciResAllocTableBase' to allow a platform
to provide its specific PCI resource allocation pool at runtime.
PCI Enumerator will allocate required resources in the range.
If the PCD is not provided, a default range will be used.

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 restricted boot flag support. When restricted boot
flag is set, the OsLoader will only try the current boot option
selected without falling through all other boot options. Also it will
not allow to get into Shell. This is for the usage to run some
critical applications such as bootloader Setup.

Current SBL supports container header verification. If the container
signature is BOOT, it will use HASH_USAGE_PUBKEY_OS. Otherwise, it
will use HASH_USAGE_PUBKEY_CONTAINER_DEF. This patch added OEM signed
container support. If a container signature between OEM0 to OEM7 is
found, it will be verified use HASH_USAGE_PUBKEY_OEM(x) where x is 0
to 7. To add an OEM public key hash, it can be done by updating
pub_key_list in GetKeyHashList() in file BoardConfig.py.
