Adds a bootstrapping script for WSL
Where we don't have a proper snapd support. Approach similar to the one used in UDI. For the case where we have Subiquity snap, but not UDI. The script added is a stripped version of the UDI one. Removed code related to: - GTK and GDK; - GI repository; - Xkb; Preserved: - Python; - XDG directory definitions; - font config;
