Add non-throwing counterparts of http.validateHeaderName() and
http.validateHeaderValue() that return a boolean instead of throwing.
Rejecting an invalid header with the existing validators costs a few
microseconds, because an error object and its stack trace are created,
compared to ~20ns for the boolean check. Userland HTTP implementations
such as undici (fetch Headers, request options) therefore keep private
copies of the token and field-value tables from _http_common. These new
functions let them reuse the core implementation.
isValidHeaderValue() accepts an optional `httpValidation` option
('strict' or 'relaxed') that has the same meaning as the option of the
same name on http.createServer() and http.request().
