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.

The current MulitBoot loading code in SBL did not follow the specification.
The spec stated "The offset in the OS image file at which to start loading
is defined by the offset at which the header was found, minus
(header_addr - load_addr)". However, the current code always copies from
offset 0 of the image file. It caused exception when loading some valid
multiboot image.

Multiboot defined framebuffer structure. However, it was not
implemented in SBL. This patch added this support by filling in
the framebuffer information into the multiboot table.
