This adds a embedder_module_hdo for identifying embedder-run modules in the dynamic import handler and import.meta initializer, and a SourceTextModuleTypes for customizing source text module compilation in the JS land via compileSourceTextModule(). Also, refactors the existing embedder module compilation code to reuse the builtin resolution logic.

There was a problem hiding this comment.
I feel like the term dynamic in ESM could be related to the dynamic import calls. Given that this creates a module with a facade, and this is also not a synthetic module, maybe we should rename it to a facade module.
Nevertheless, this is not a blocker for this PR.
