Instead of tracking columns during lexing, which costs performance for something that will only be required in the unexpected failure path, we now only track the line numbers and calculate the column on demand when an error occurs. As part of this we also fix GH-22487 by adjusting the logic to report the column based on the (UTF-8) column in the source, instead of treating `\uXXXX` escapes as a single column, which users will need to count manually instead of being able to rely on their editor or `mb_substr()` or similar.
