introduce gb_Module_SKIPTARGETS

- this speeds up the old SKIP_TESTS targets build-nocheck and
  dev-install-nocheck
- this allows e.g. tinderboxes, which know that they just completed a
  build, to only read the files for the tests (and exclude the build
  itself)
- since the dep file can be quite large this might help performance in
  such scenarios quite a bit
- also moving this to extensions as it is merely a performance
  optimization
