Move net::FormatUrl and friends outside of //net and into //components

net::FormatUrl and related are specifically concerned with display
policies of URLs, which is not something that //net needs to be aware
of, as that's a UX question.

This folds in net::FormatURL along with the existing //components/url_fixer
and //components/secure_display into a common component,
//components/url_formatter, that handles reformatting URLs for user-friendly
or data storage (url_formatter), for use in security prompts (elide_url),
or for reformatting URLs from user input (url_fixer)

(Disabling presubmit since this is intentionally not fixing a legacy API, just moving it for future cleanups)
