This change adds a module map for libstdc++, which allows it to be properly imported into Swift as a module. The module map is installed into `usr/lib/swift/linux/{arch}` similarly to `glibc.modulemap`, and is passed to Clang as `-fmodule-map-file`.
That means it is now possible to import std directly from Swift on Linux, when C++ interop is enabled.
The module map currently declares a single `std` module without splitting the headers into submodules. This is going to change in the near future.
