_replace_prefix_bin performance improvements (#33590)
- single pass over the binary data matching all prefixes
- collect offsets and replacement strings
- do in-place updates with `fseek` / `fwrite`, since typically our
replacement touch O(few bytes) while the file is O(many megabytes)
- be nice: leave the file untouched if some string can't be
replaced
