This reverts r72978, 72984, 72989 and 72992. Do not use wxNOEXCEPT for wxTextCtrl dtor as this breaks compilation of any user-defined classes inheriting from it unless they use wxNOEXCEPT as well and the benefits (fixing a harmless warning for the niche ICC compiler) are just not worth the compatibility breakage. See #14826. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@72993 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
