Revert "core: don't include_str extension js code (#10786)" (#14614)

This reverts commit 10e50a120744de71d6915af4ae93f8231607573d

Alternative to #13217, IMO the tradeoffs made by #10786 aren't worth it.

It breaks abstractions (crates being self-contained, deno_core without snapshotting etc...) and causes pain points / gotchas for both embedders & devs for a relatively minimal gain in incremental build time ...

Closes #11030
