Subject: [PATCH] cmake: add _extra_files IDE target from heuristics

Lots of files in the repos are not included into the generated IDE
projects. Therefore we add utility targets (custom targets), which are
populated by glob patterns, which should fit most files that are found
in qt's subprojects.

Pick-to: 6.7
