Subject: [PATCH] feat(core): manually annotate de-sugarred core tree-shakable
 providers with @pureOrBreakMyCode (#41096)

This is necessary for closure compiler in order to support cross chunk code motion.

I'm intentionally not annotating these call sites with @__PURE__ at the moment because
build-optimizer does it within the Angular CLI build. In the future we might want to consider
having both annotations here in case we change how build-optimizer works.

PR Close #41096
