add a clangd/clangdall and qtcreator/qtcreatorall make targets

Add a clangd make target:
$ make clangd
This installs a .clangd file with configuration (includes/macros/compiler flags)
for the clandg language server.

Add a clangdall make target:
$ make clangdall
This installs a .clangd also in pikotools/ezc/morm and tito libraries.

Add a qtcreator make target:
$ make qtcreator
This installs a .qtcreator directory with QTCreator IDE project files.
In the QTCreator you can open a project by selecting the .qtcreator/winix.creator
file.

You can use 'make qtcreator' again to refresh .qtcreator/winix.files,
the rest of the project files will not be modified.

Add a qtcreatorall make target:
$ make qtcreatorall
This installs a .qtcreator directory also in pikotools/ezc/morm and tito libraries.
