[tmodes <2123873@xxxxxxxxxxxxxxxxxx>]

I've taken the route to remove all deprecated wxT macros at all. So this should also fix these issues here.
Please report back if it compiles fine and works for you.

Title:
  wxWidgets 3.3 compatibility

Status in Hugin:
  Fix Committed

Bug description:
  I tried compiling 2024.0.1 against wxWidgets 3.3.1

  It needed the already committed changes for non-literal msgids:
  https://sourceforge.net/p/hugin/hugin/ci/1e5e4a74970bd7608e8a796ec56e303e7799d29c/

  Plus there are some errors caused by string concatenations due to changes to operators on wx types
  https://raw.githubusercontent.com/wxWidgets/wxWidgets/v3.3.0/docs/changes.txt

  e.g.

  hugin-2024.0.1/src/hugin1/base_wx/StitchingExecutor.cpp:454:40: error: no match for ‘operator+’ (operand types are ‘const wchar_t [4]’ and ‘std::string’ {aka ‘std::__cxx11::basic_string<char>’})
    454 |             nonaArgs.Append(wxT("-z ") + opts.outputLayersCompression + wxT(" "));
        |                                        ^ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~
        |                                               |
        |                                               std::string {aka std::__cxx11::basic_string<char>}

  These errors could be resolved by removing the obsolete since wxWidgets 2.9 wxT()'s in those concatenations
