Complete coding to support X64 EFI ABI in UnixPkg. Code is not currently hooked in or tested, but it is code complete. Only missing step from testing is figuring out how to build with two different ABIs for the same platform. Sec needs a different ABI. May need to add a 2nd build step.

# Efi Prefix means it has been ported to gasket EFIABI to Unix x86_64 ABI

# The EFI_UNIX_THUNK_PROTOCOL member functions call these these generic assembly
# routines.
#
# Some OS X POSIX calls get name mangled in C code and we need to fill in a C global
# to get the correct binding (does not work from assembly). So we have 4 functions
# that do an indirect call, while the others call POSIX APIs directly
