Patrick Walton e8d6031c71 libsyntax: Forbid escapes in the inclusive range \x80-\xff in
Unicode characters and strings.

Use `\u0080`-`\u00ff` instead. ASCII/byte literals are unaffected.

This PR introduces a new function, `escape_default`, into the ASCII
module. This was necessary for the pretty printer to continue to
function.

RFC #326.

Closes #18062.
