Build minmdns examples with build_examples.py (project-chip#11735)

* Add target and make minmdns compile

* Update output logic to support multiple outputs per app

* Fix output names

* Update how output names are yielded

* Restyle fixes

* Update the build logic: targets decide options, no need for extra RPC guards. Fix rpc artifact names

* Fix unit tests

* Allow rpc console to be built natively only

* Restyle fixes
