Don't interpret '&' specially in wxTextWrapper.

wxTextWrapper is used for the multiline text for which it doesn't make sense
to use mnemonics so don't interpret '&' specially in the text used with it.

Doing this also allows to remove the hack used in wxDialog::CreateTextSizer()
to deal with it that was used so far.
