Alexandre Poirot 94b0ede386 Bug 1793604 - [devtools] Inject JSM/ESM globals directly from Loader.jsm/sys.mjs. r=jdescottes
ESM can't be loaded while loading.
So that Loader.jsm/sys.mjs can't load builtin-modules.js with itself loading Loader.jsm/sys.mjs.
We do that in order to inject JSM/ESM globals from builtin-modules.js.
Let's instead inject the few globals of JSM/ESM directly from Loader.

This isn't ideal, but as Loader is meant to be removed when moving to ESM...
