John Hui 1fe7f685b5 [cxx-interop] Import __int128 as CInt128 ...

Swift gained native Int128 / UInt128 types in SE-0425, but the plumbing
for bridging them across the C/C++ boundary was incomplete. CInt128 and
CUnsignedInt128 were never added to CTypes.swift, even though
BuiltinMappedTypes.def has been mapping __int128 / unsigned __int128 to
those names since 2013. Without the typealiases, every C declaration
mentioning __int128 was silently dropped at import time.

This patch adds the CInt128 and CUInt128 type aliases to CTypes.swift
for forward interop, and also adds the Int128 -> __int128 mapping in
PrintAsClang and IRABIDetailsProvider for reverse interop.
