We require API compatibility in the ngspice library because we
dynamically load the library and assign function pointers to specific
names/signatures. This should be consistent for all versions of the the
library until the soversion changes.

(cherry picked from commit 17a17586a6)
The config.h header for ngspice is not packaged with all platforms so
use pkg-config to fetch the version information when available. When
pkg-config is not available, check if the ngspice/config.h file is
installed on the system before including it to build the ngspice version
string. If neither pkg-config or ngspice/config.h is available set the
version string to "unknown".

Some developer scripts ended up in the demonstration scripts directory
that was bundled with builds. This moves them to the build_tools
directory and updates the associated Documentation
Fixes: lp:1815891
* https://bugs.launchpad.net/kicad/+bug/1815891
Adds a link-time dependency for libngspice, so that other tools may
detect ngspice as a KiCad dependency.
The library is still loaded with dlopen() as it gives a way to reload it
in case of problems. The DLL name is recognized during CMake
configuration and used to load the library at runtime.
