pw_tokenizer: Make Base64 encoding easier to use

- Have PW_TOKENIZER_CFG_ENCODING_BUFFER_SIZE represent the whole encoded
  buffer, including the 4-byte token. This makes the value easier to use
  directly since the token is already accounted for.
- Update the Base64 encoding functions to always add a null terminator
  to the Base64 output.
- Provide a pw::tokenizer::PrefixedBase64Encode overload that allocates
  the buffer using pw::Vector.
