Subject: CMakePM: Treat header files as project files

CMake doesn't associate header files in a compiler group in the
file-api export. But it does list them as source files if added
to the source files of a target.

By using the CppEditor::ProjectFileCategorizer we can sort the
header files to the right compiler group.

This way one could have the clang-tidy and clazy run on a header
file. Or the TODO plugin find TODOs in header files. Or the Autotest
plugin finding Google Tests in header files.
