SSR (@lit-labs/ssr)

Description

Issue was raised by Justin here: #4515 (comment)

Because ssr depends on its own lit-html, there is the possibility that the version of lit-html that ssr imports is minified, while the templates/directives being SSR'd are not minified, or vice-versa. E.g. if a library being SSR'd has its own bundled Lit.
