Adding the "Skip Changelog" label as this PR has no user-observable changes.
Hmm, I'm gonna go back to draft.
Internal tests of the new polyfills including this PR passed so I think this is ready for review now. (custom elements: http://cl/475617405, webcomponentsjs: http://cl/475619724)
Thanks for the review!
This PR upstreams a couple of internal CLs that added
any
in a few places to make this code compatible with a newer version of TypeScript (4.4 I think?). The PR then updates TypeScript to the latest version and makes other type changes to work with that version.
