Remove QFtp sources etc. in favor of alternate distribution

While we initially wanted to just disable the functionality the way it
is currently built forces people to do a full build of Qt just to enable
it. Instead of doing this half-measure let's just remove the code
completely from QtBase and rather prepare QtNetwork to handle being a
plugin that can be compiled at any time.

Task-number: QTBUG-80340
