* added CMake option `DISABLE_DMAKE` to disable `run-dmake` dependencies
* tools/CMakeLists.txt: added TODO
* use `ccache` for sanitizer builds
* aligned selfcheck between sanitizer workflows and disabled some currently unnecessary steps
* CI-unixish.yml: do not use precompiled headers with `ccache`

In tools/, it did not understand that some files are generated by
matchcompiler.py.
