Subject: Reapply "[Feature #6012] Extend `source_location` for end position

* This reverts commit 065c48cdf11a1c4cece84db44ed8624d294f8fd5.
* This functionality is very valuable and has already taken 14 years
  to agree on the API.
* Let's just document it's byte columns (in the next commit).
* See https://bugs.ruby-lang.org/issues/21783#note-9
