Extension for CMake Presets

Released version with CMake Presets can be upgraded to add some useful features. Some of them are:

1. User should be able to specify his user file instead of being forced to edit user.json file and user_options.json.
2. Overwrite should be stop/have a warning in case of several CMakeUserPresets.json in the same folder.
3. The documentation readme-docs/Presets-advanced.md should be edit to fit with the new CMake Presets format to be relevant.
4. Move user.json, user_options.json and the script to a separate folder.
5. Later, move the script into a separate repository. Adapt the documentation to be completly independent from the proxy-geos.
6. Add the possibility of multiple inheritage. For example, it would be possible to specify "a+b" to inherit from preset "a" and "b".
7. Job parallelism should be free to users and not hard coded in the script (one good way could be to use inheritage in build presets to inherit from a helper presets, here to define some general properties of build presets. This could also be done for test presets to specify general properties.)
8. Linked to the previous one, user can write base presets for test, build or configure that will be inherited by generated presets (Can be used for optimization -O discussion)
