refactor(data_structures): CodeBuffer::print_bytes_unchecked take a…

… byte slice (#9327)

Alter signature of `CodeBuffer::print_bytes_unchecked`, to take a byte slice instead of an iterator.

This would be a breaking change, but `CodeBuffer` was only made public in last PR (#9326), so no-one will have had a chance to depend on it yet!
