related fdo#70414 gbuild to ide: kdevelop

This provides kdevelop integration and generates one project file for each
old-style module (top level dir). This project file has:

- has four build configurations:
- build the module of the project or build all of LibreOffice
- for each of the above a debug and a nondebug build
- has seven launch targets:
- running the unitchecks, the slowchecks and subsequentchecks
- for each of the above once for the module and once for all
- running LibreOffice interactively
- has custom include paths and thus provides full autocompletion
