pw_tokenizer: Use facades for global handlers
Previously, pw_tokenizer conditionally enabled the global handlers with
macros. The default was that they were enabled, which meant handlers had
to be defined, even if they weren't used.
This change moves the two global handlers from the core pw_tokenizer
library to separate facades. This allows projects to define only the
global handlers they need.
