Increment parser timestamp when narrowing changes (bug#67977)
When narrowing changes, parse reparses, so the timestamp should
definitely increment, just like in ts_record_changes.
Failing to increment this timestamp, outdated nodes would think they
are still up-to-date, and try to print their type name. Printing
their type name involves accessing the old parse tree, which is
already freed during the last reparse.
I also found that we don't increment timestamp when changing parser
ranges and fixed that as well.
