Reorganizing structure to have Module/TK/Package/FILES structure. New structure reflect the structure inside IDE. Migrate FILES, PACKAGES, EXTRLIB to CMake version to handle changes on updates. No changes were done to installation layout, all installation result keep as before. The migration was done using python script, see PR, which refactor automatically the structure. Updated doc generation to have valid path to modules, toolkits and packages. In case of PR into new version, IR-790 can be used as a target for the previous version.
