Niels Lohmann f6c115a9a6 Move the float conversion chain out of the lexer ...

lexer::convert_number() converted float tokens with std::from_chars (when
available), Clinger's fast path, and the locale-aware strtod fallback, all
as lexer members. They are now free functions in number_parse.hpp:

- convert_float_fast(): std::from_chars, then Clinger's fast path, skipped
  when the mantissa has too many significant digits
- convert_float_locale_aware(): strtof/strtod/strtold with the decimal point
  of the current locale, retried when the locale changed (#5198)

so that other code converting JSON number tokens gets the same values. No
change in behavior; the lexer no longer includes <clocale> and <cstdlib>.
