Split the `internal/process/esm_loader` file which contains the singleton cascaded loader: - The the singleton cascaded loader now directly resides in `internal/modules/esm/loader`, where the constructor also lives. This file is the root of most circular dependency of ESM code, (because components of the loader need the singleton itself), so this makes the dependency more obvious. Added comments about loading it lazily to avoid circular dependency. - The getter to the cascaded loader is also turned into a method to make the side effect explicit. - The sequence of `loadESM()` and `handleMainPromise` is now merged together into `runEntryPointWithESMLoader()` in `internal/modules/run_main` because this is intended to run entry points with the ESM loader and not just any module. - Documents how top-level await is handled.
