Draft: [feat] Add slam-standalone packaging

This is a draft (POC) MR showing a way to "package" the lidar slam library.

To test it:

mkdir build
cmake -S lvsb/standalone-slam/ -B build -GNinja
cd build && ninja -j8
ctest .

Multiple things to know:

• It does not package the paraview wrapping of the slam (it does not share the same purpose).
• Before merging we should create a custom LidarSlam-Config.cmake to help cmake find the library and includes.
• It was not tested with an other installed pcl - conflicts may occurs with slam's pcl.
