std.Build: Install Windows DLLs to `<prefix>/bin/` by default

Windows does not support RPATH and only searches for DLLs in a smallnumber of predetermined paths by default, with one of them being thedirectory from which the application loaded.

Installing both executables and DLLs to bin/ by default helps ensurethat the executable can find any DLL artifacts it has linked to.DLL import libraries are still installed to lib/.

These defaults match CMake's behavior.
