UefiPayloadPkg/BlSupportDxe: fix ReserveResourceInGcd() calls
    
    The last parameter of ReserveResourceInGcd() is "ImageHandle", forwarded
    in turn to gDS->AllocateMemorySpace() or gDS->AllocateIoSpace() as "owner"
    image handle.
    
    But BlDxeEntryPoint() passes "SystemTable" as "ImageHandle".
    
    Compilers have not flagged it because EFI_HANDLE (the type of
    "ImageHandle") is unfortunately specified as (VOID*), and
    (EFI_SYSTEM_TABLE*) converts to (VOID*) silently.
    
    Hand the entry point function's "ImageHandle" parameter to
    ReserveResourceInGcd(). This fixes an actual bug.
