[issue13604] update PEP 393 (match implementation)

[Jim Jewett]

New submission from Jim Jewett <jimjjewett at gmail.com>:

The implementation has a larger state.kind
Clarified wording on wstr_length and surrogate pairs.
Clarified that the canonical "data" format doesn't always have a data pointer.
Mentioned that calling PyUnicode_READY would finalize a string, so that it couldn't be resized.
Changed section head "Other macros" to "Finalization macro" and removed the non-existent PyUnicode_CONVERT_BYTES (there is a similarly named private macro).
