Bugzilla: 1536624

In a later patch in this series, we're going to resurrect "inet_pton.c"
(originally from the StdLib package). That source file has a number of
standard C and BSD socket dependencies. Provide those dependencies here:
- The header files below will simply #include <CrtLibSupport.h>:
- arpa/inet.h
- arpa/nameser.h
- netinet/in.h
- sys/param.h
- sys/socket.h
- EAFNOSUPPORT comes from "StdLib/Include/errno.h", at commit
e2d3a25f1a31; which is the commit immediately preceding the removal of
StdLib from edk2 (964f432b9b0a).
Note that the other error macro, which we alread #define, namely EINVAL,
has a value (22) that also matches "StdLib/Include/errno.h".
- The AF_INET and AF_INET6 address family macros come from
"StdLib/Include/sys/socket.h".
- The NS_INT16SZ, NS_INADDRSZ and NS_IN6ADDRSZ macros come from
"StdLib/Include/arpa/nameser.h".
- The "u_int" and "u_char" types come from "StdLib/Include/sys/types.h".
