[roll third_party/pigweed] pw_tokenizer: Support arbitrary recursion in C++ detokenizer

- Rename DetokenizeBase64() to DetokenizeText() for consistency with
  Python and since it will eventually support the full nested token
  format.
- Support arbitrary nested tokenization recursion depth for
  DetokenizeText().
