REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3818

It will have some potential issue when memory larger than 2G because
the high memory address will be fill with 0xFFFFFFFF when do the
operation of INTN + INT64 but it is 32 bit normal data in fact.

Should use same data type INT64 + INT64.

V3:
1. Use INT64 as input parameter because all date type is 64 bit
V2:
1. Force the data type to UINTN to avoid high dword be filled with
0xFFFFFFFF
2. Keep INTN because the offset may postive or negative.
