mintro: Introspection interpreter refactoring (#4733)

* Fixed spelling

* Merged the Buildoptions and Projectinfo interpreter

* Moved detect_compilers to Environment

* Added removed test case

* Split detect_compilers and moved even more code into Environment

* Moved set_default_options to coredata

* Small code simplification in mintro.run

* Move cmd_line_options back to `environment`

We don't actually wish to persist something this unstructured, so we
shouldn't make it a field on `coredata`. It would also be data
denormalization since the information we already store in coredata
depends on the CLI args.
