Add new targets to the Makefile:
- forceclangd - allow to force installing a .clangd file
- forceclangdall - force installing .clangd file in this project and in libriaries:
  pikotools, morm, ezc and tito
- forceqtcreator - force installing qtcreator files
- forceqtcreatorall - force installing qtcreator files in this project and in libraries
Existing files will be overwritten.

- update the c++ standard to c++23
