Fail earlier on Windows.

App dependencies are now analysed on app enable as well - not only on app install.

There is a setup check that prevents installing on Windows.
No need to keep the old unsupported Windows code paths.

Also fix the posix test that was running the wrong verify method:

The call to UserList.add() was wrong and was passing "user.lastLogin"
as the sort argument which would cause the list to be resorted over and
over again for every added item after loading the next page of users.

Fixes incorrect loading of file when using the console from a sibling OC instance directory (#26301)

The check for two factor enforcement would return true for non-existing
users. This fix makes it return false in order to be able to perform
the regular login which will then fail and return false.

This prevents throwing PasswordLoginForbidden for non-existing users.
