Consolidate emitted IL for-loop tests (#17128)

* Consolidate emitted IL `for`-loop tests

* The test sources and baselines for these were duplicated in #15484 to
  test the realsig feature, but that meant that the test _sources_
  needed to be kept in sync by hand. This change uses the approach used
  in #16795 instead: it reuses the same test _source_ files and just
  adds duplicate _tests_ to check the emitted IL with realsig+.

* Update netfx baselines

* Fix find/replace bug

* Unify netstandard assembly version in IL

* Re-update baselines
