build: add a workaround for reflection test on Windows
build: add a workaround for reflection test on Windows

Copy the runtime component into the swift runtime directory.  Normally
the runtime directory is not the same as the library directory on
Windows.  This copies the runtime component into the build tree into the
runtime directory to permit the tests to find the standard library.
