HTML API: Reliably parse HTML in get_url_in_content()

Browse Source 
As part of a larger effort in #63694, this utlizes `WP_HTML_Tag_Processor` instead of regex to parse the string passed into `get_url_in_content`.

As a benefit this also decodes the URL whereas the previous code didn’t, so strings like `http://` will be properly decoded as `http://`.

Developed in: https://github.com/WordPress/wordpress-develop/pull/9272
Discussed in: https://core.trac.wordpress.org/ticket/63694
