✨ Add minimal working swctl utility

Takes only swctl.py script from https://gitlab.com/sat-mtl/tools/switcher/-/tree/fix/revive-swctl branch.

Move it to tools/swctl path so CMake installer install command to /usr/local/bin/swctl and become available in path.

Fix quid_id now taking string instead of integer (to allow for new UUID quiddity ID).

Leave behind any outdated pyquid changes proposed by fix/revive-swctl branch. swctl was tested to at least list kinds, list quiddities, create quiddity, get and set boolean property.✨
