wxwidgets: restructure into one folder

It’s easier to manage these in one folder.

Affected folders from pkgs/development/libraries/:

- wxGTK-2.8
- wxGTK-2.9
- wxGTK-3.0
- wxmac

These will all go into pkgs/development/libraries/wxwidgets for now.

pkgs/development/libraries/wxwidgets/2.9/default.nix
