This change moves the logic for constructing DevTools endpoint URLs into
a common location (DevToolsHttpEndpoint). Call sites that were
previously building URL strings directly can now call the appropriate
method on DevToolsHttpEndpoint instead. For example, List() returns
an endpoint's /json/list URL.

A DevToolsHttpEndpoint can be constructed from a NetAddress for the
common case where the endpoint is running on localhost on a certain
port. It can also be constructed from a URL with a path prefix. The
prefix will be included in all URLs for that endpoint.

This is mainly to support some downstream features in MSEdgeDriver that
rely on devtools endpoints with path prefixes and which may be served
over HTTPS. There is no functional change to ChromeDriver. Just some
refactoring.
