Intent to Migrate trusted-types to W3C Security WG

Hi all!

I wanted to propose migrating Trusted Types from WICG to W3C to be
adopted by the Security WG.

The specification [1] is already in what we believe is a decent shape, the
Chrome implementation follows. There are some open issues [2], but I
believe we can discuss them in the WG.

We are piloting the API at Google - other authors are piloting this though
Chrome Origin Trials. There's positive signals from the JS community as
well - and indeed the API seems to be working well, as we've added several
new features to help with its adoption.

I spelled out the Intent to Migrate as a bug as required [4]. It should
have more context about the API and the reasoning behind migration intent.
I'm open to questions and complaints on this thread, or directly in the
GitHub issue.
