These are not needed after #35129 but making uncrustify still play nice
with them was a bit tricky.
Unfortunately `uncrustify --update-config-with-doc` breaks strings
with backslashes. This issue has been reported upstream,
and in the meanwhile auto-update on every single run has been disabled.
Problem: Vim script debugger functionality needs cleanup.
Solution: Move debugger code to a separate file. Add more tests. (Yegappan

Good to have for eval_expr_restore in v8.2.3417.
Doesn't actually add any tests.
