Don't try to center task dialogs under Windows.

This is either unnecessary or doesn't work anyhow (they are always centered on
the parent window) and just results in debug error messages.

Simply don't do anything in wxMessageDialog::Centre() when using task dialog
implementation under MSW.

Closes #12699.
