Bug #14919: Add String#byteinsert

----------------------------------------
It's important for multibyte String editing. Unicode grapheme characters sometimes have plural code points. In text editing, software sometimes should add a new code point to an existing grapheme character. String#byteinsert is important for it.

I implemented by pure Ruby in my code.
