CalculateCrc32 Boot Services as defined in DXE CIS.
This Boot Services is in the Runtime Driver because this service is
also required by SetVirtualAddressMap() when the EFI System Table and
EFI Runtime Services Table are converted from physical address to
virtual addresses. This requires that the 32-bit CRC be recomputed.
