Subject: [PATCH] Corrade: Drop vs2017 workaround when building HEAD for vs2019
 (#7566)

* Corrade: Make sure to drop vs2017 workaround when building HEAD for vs2019

Otherwise building HEAD is broken.

Also add a warning about current Corrade release not supporting vs2019,
suggesting to use HEAD instead.

* [corrade] this option name is wrong.
