Replace json_spirit with nlohmann json v3.12

Browse source 
json_spirit is no longer maintained, as all links inside
the third_party folder are going to nirvana. Also most projects
on github did not see any commits in at least 6 years. Switching
to nlohmann JSON should allow to maintain this part more easily in
the future.
Add nlohmann-json as a external lib through build-libraries. Create
a include-only library target in extern_libs5.lua. On Linux and BSD, the
system version is used.
Add switch to build with system-nlohmann-json.
Update debian-12 dockerfile to include nlohmann-json.

This separate JSON library is used for Atlas to avoid the SpiderMonkey dependency.
SpiderMonkey is a fully featured JS engine and even though we already use it for the main engine, it's too heavy-weight to use it in Atlas.
The SpiderMonkey API also changes frequently and we hope that the JSON parsing code needs less changes when we use this separate library.
Get the library from here:
http://www.codeproject.com/Articles/20027/JSON-Spirit-A-C-JSON-Parser-Generator-Implemented
The currently used version was released on the 10 of May 2014.
Search for this comment in json_spirit_value.h and uncomment the lines we don't need:
// comment out the value types you don't need to reduce build times and intermediate file sizes
