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.
