Refactor `printMinimalImports` into two functions and reexport them
Currently the printMinimalImports function finds set of minimal imports and prints them into file.
But it's more convenient to have function that returns set of minimal imports that can later be used by external tools like source plugins without need to parse content of .import file. And without need to copy-paste existing function.
