Mathieu Fenniak 9fe0cbee02 fix: relocate PR review comments using git blame --reverse, improving comment placement (#12015)
When a review comment is placed on a PR in Forgejo, Forgejo performs a `git blame` to identify which commit originated the line, and records that commit and line number in the comment's database record.  Later when the review is viewed, Forgejo currently makes no effort to place that comment in the correct *current* location, which may vary -- for example, if a PR had two commits and the comment was made on a line in the first commit, but the second commit changes line numbers in that file, the comment will appear in the incorrect location.

This PR adds the usage of `git blame --reverse` to calculate the correct location to display the comment in the current view (whether reviewing the PR commit-by-commit, or "Files changed").  It certainly does not fix all problems with comment placement (see comments).

Another major addition in this PR is a test harness for making relatively complex PRs and reviewing the diffs on the per-commit view and PR-diff views.
