Deprecate FTP support

Deprecate and remove support for FTP URLs.

The current FTP implementation in Google Chrome has no support for encrypted connections (FTPS), nor proxies. Usage of FTP in the browser is sufficiently low that it is no longer viable to invest in improving the existing FTP client. In addition more capable FTP clients are available on all affected platforms. Google Chrome 72+ removed support for fetching document subresources over FTP and rendering of top level FTP resources. Currently navigating to FTP URLs result in showing a directory listing or a download depending on the type of resource. A bug in Google Chrome 74+ resulted in dropping support for accessing FTP URLs over HTTP proxies. Proxy support for FTP was removed entirely in Google Chrome 76. Remaining capabilities of Google Chrome’s FTP implementation are restricted to either displaying a directory listing or downloading a resource over unencrypted connections. We would like to deprecate and remove this remaining functionality rather than maintain an insecure FTP implementation.
