This commit adds: - `addAbortListener` in `node:events` - `aborted` in `node:util` - `execPath` and `execvArgs` named export from `node:process` - `getDefaultHighWaterMark` from `node:stream` The `execPath` is very hacky - because module namespaces can not have real getters, `execPath` is an object with a `toString()` method that on call returns the actual `execPath`, and replaces the `execPath` binding with the string. This is done so that we don't require the `execPath` permission on startup.
