module: move callbacks and conditions into
Browse files Browse the repository at this point in the history
This moves the following utils into modules/esm/utils.js:

- Code related to default conditions
- The callbackMap (which is now created in the module instead of
  hanging off the module_wrap binding, since the C++ land
  does not need it).
- Per-isolate module callbacks

These are self-contained code that can be included into the
built-in snapshot.
