Improve buildIdris and expose the idris2-api via the Nix flake. (#3182)
* Refactor buildIdris slightly and support installing libraries with source. Add the Idris2 API package as an output of the flake.

* update templates and simplify construction of a search path.

* use newer method of specifying default package

* swap out trace function for warn function. fix warnings in template generation
