This patch makes the top-level access to runtime states in the
CJS loader lazy, and move the side-effects into a
initializeCJS() function that gets called during pre-execution.
As a result the CJS loader can be included into the built-in
snapshot.

Preload essential modules and lazy-load non-essential ones.
After this patch, all modules listed by running this snippet:

```
const list = process.moduleLoadList.join('\n');
require('fs').writeSync(1, list, 'utf-8');
```

(which is roughly the same list as the one in
test-bootstrap-module.js for the main thread)
are loaded from the snapshot so no additional compilation cost
is incurred.

    [snapshot] Dont defer ByteArray when serializing

    JSTypedArray needs the base_pointer ByteArray immediately
    if it's on heap. JSTypedArray's base_pointer was initialized
    to Smi::uninitialized_deserialization_value at first when
    deserializing, and if base_pointer was deferred, we will
    mistakenly check JSTypedArray not on heap.

It turns out that even with startup snapshots, there is a non-trivial
overhead for loading internal modules. This patch makes the loading
of the non-essential modules lazy again.

Caveat: we have to make some of the globals lazily-loaded too,
so the WPT runner is updated to test what the state of the global
scope is after the globals are accessed (and replaced with the
loaded value).

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
