Implement String#append_as_bytes(String | Integer, ...)
[Feature #20594]
A handy method to construct a string out of multiple chunks.
Contrary to `String#concat`, it doesn't do any encoding negociation,
and simply append the content as bytes regardless of whether this
result in a broken string or not.
It's the caller responsibility to check for `String#valid_encoding?`
in cases where it's needed.
When passed integers, only the lower byte is considered, like in
`String#setbyte`.
