LibURL: Add 'about:XXX' helper factory functions

Currently we create URLs such as 'about:blank' through the StringView
or ByteString constructor of URL. However, in order to elimate the
use of URL::is_valid, we need to get rid of these constructors as it
makes it way too easy to create an invalid URL.

It is very cumbersome to construct an 'about:blank' URL when using
URL::Parser::basic_parse. So instead of doing that, create some
helper functions which will create the 'about:XXX' URLs with the
correct properties set.

Conveniently, this is also a much faster way of creating these URLs
as it means we do not need to parse the URL and can set all of the
members up front.
