Revert "LP#1709710 Count Perl chunk/bundle sizes in bytes"

This reverts commit be2b2645f7da0907366eb0c99b5d6c231c366b30.

"It's not necessary. we don't actually put 2+ byte chars in json strings
we publish.  we always \u-escape them. so bytes == chars for json we
publish.  So, it's not only unnecessary, but it's confusing for future
us'es."
