[edk2] [PATCH v2 1/6] BaseTools/CommonLib: avoid using 'native' word size in IP address handling

[Ard Biesheuvel]

In the context of the BaseTools, there is no such thing as a native word
size, given that the same set of tools may be used to build a firmware
image consisting of both 32-bit and 64-bit modules.

So update StrToIpv4Address() and StrToIpv6Address() to use UINT64
types instead of UINTN types when parsing strings.
