This allows authors to check if a Trusted Type is required for the given Elements property. This adds 28 more passing WPT tests :)
The TrustedHTML interface represents a string that a developer can confidently insert into an injection sink that will render it as HTML. These objects are immutable wrappers around a string, constructed via a TrustedTypePolicy’s createHTML method.
This is used to check the legitimacy of a TrustedHTML object.
It is mostly a skeleton with no actual implementation.
It simply consists of a wrapper around the main algorithm
This is the mechanism that should pages to determine what kind of policies can be created on their domains mostly based around the HTTP headers the server responds with.
This is the main mechanism by which users of the api can create safe object with a callback for any needed sanitation of the values.
This turns out to be very similar to TrustedHTML.
This changes should allow us to now call createScript as well.
This completes the 3 main TrustedType classes.
This gives us at least 72 new tests :)

This is a continuation of the work started in #5430
This time the focus is on being able to create policies via
TrustedTypePolicyFactory::create_policy& being able to created TrustedTypes withTrustedTypePolicy::create_(html|script|script_url)This unluck a good set of wpt tests in the trusted-types section.
My plan is to focus next on integrating this with the injection sinks api.
