refactor(downloader): introduce top-level downloader module

Move VCS downloaders and DownloadManager out of vcs/repository into a
new top-level downloader module mirroring Composer\Downloader, and add
stub types for the remaining Composer downloader hierarchy (file,
archive variants, path, perforce, fossil, exceptions, interfaces) so
future ports have a home.
