6703 - new types: code-point and grapheme

Both have the same size: 4 bytes.

So far I've just renamed print-byte to print-grapheme, but it still behaves
the same.

I'm going to support printing code-points next, but grapheme 'clusters'
spanning multiple code-points won't be supported for some time.
