refactor(core): InternalModuleLoader checks if all files were used (#18005)
This commit changes "InternalModuleLoader" from "deno_core" to store a list of used modules during snapshotting. If a module was not used during snapshotting "InternalModuleLoader" will panic in its "Drop" handler signaling to the embedder that they made a mistake somewhere.
