1790483 - Add basic lit vendoring for use in new widgets

Status: RESOLVED FIXED

(Firefox :: General, task)

Description

[Hanna Jones [:hjones]]

We want to experiment with using the lit library for building out some new reusable components for Firefox.

For now it might be sufficient to just include the minified lit source available as a single file at https://cdn.jsdelivr.net/gh/lit/dist@2/all/lit-all.min.js

We will need to patch some usage of innerHTML which will otherwise gets sanitized and break lit-html. Otherwise this should provide us with a quick way to get started with using lit in central.

This adds a new lit.all.dev.mjs file which is the development version of lit.
It is unminified so we can more easily see changes between updates. For official
builds, we use a version that is locally minified by esbuild. It's still the
development version though, so we'll still see the dev warning.

Depends on D159765
