REF:https://bugzilla.tianocore.org/show_bug.cgi?id=3793
Basede on UEFI Spec 2.0 section 17.7.1 structure
EFI_GRAPHICS_OUTPUT_PROTOCOL_MODE say FrameBufferSize should be size of
UINTN, in MdePkg\Include\Guid\GraphicsInfoHob.h
EFI_PEI_GRAPHICS_INFO_HOB FrameBufferSize is UINT32,

UefiPayloadPkg\GraphicsOutputDxe\GraphicsOutput.c
MdeModulePkg\Universal\Console\GraphicsOutputDxe\GraphicsOutput.c

Private->GraphicsOutputMode.FrameBufferSize = \
GraphicsInfo->FrameBufferSize;

UINT32 value is getting assigned to UINTN,
in X64 build compiler will throw possible loss of data error.

so update the EFI_PEI_GRAPHICS_INFO_HOB based on UEFI Spec 2.0
