Use t_str() instead of wx_str() to make the code work correctly in UTF-8 build
in which wx_str() returns a pointer to UTF-8 buffer while we need a wchar_t
pointer for Windows.
Closes#14371.

This is a generalization of wxMessageDialog based on the native task dialog
under recent (Vista and later) Windows versions and implemented generically
for the other ports for now.
It provides the possibility to use additional controls in the message boxes
(checkbox useful for the "Don't ask me again" kind of dialogs and collapsible
detailed explanations field) and better look and feel under Windows.
