Support for :perl, :perlfile, :perldo and perleval() (#12809)

Browse Source 
* support for :perl, :perlfile, :perldo and perleval()

* document that the perl provider doesn't currently work on Windows

* document that the perl legacy interface is now also supported

* added perleval() documentation

* import legacy perl interface tests

* only perl 5.22+ is supported

* healtcheck: use g:perl_host_prog if its set instead

using just 'perl' isn't correct as it may not be the version requested.
ditto for 'cpanm', rather go through 'App::cpanminus' to find the latest
perl version
