Fix wxMSW wxDateTimePickerCtrl build with wxUSE_UNICODE_UTF8

Browse Source 
Don't use the ternary operator as t_str() doesn't return a pointer in
this build configuration.

Also remove outdated (and maybe even wrong) comment about MinGW headers,
as it's better to use a temporary variable just to avoid writing the
cast explicitly anyhow.

Closes #19338.
