This makes some of the internal `AsyncWrap::MakeCallback()`
utility wrappers throw rather than crash the process when
the requested method is not present on the `this` object.

Doing so makes it easier for future code to expose C++
objects directly to userland, where JS code can overwrite
or delete such methods.

Previously, the `Environment` destructor did not release its
`fs_stats_field_array` memory. The memory is allocated when the
`fs` module is initialized and calls `GetStatValues()`.

This adds pairs of methods to the `Environment` class and to public APIs
which can add and remove cleanup handlers.

Unlike `AtExit`, this API targets addon developers rather than
embedders, giving them (and Node’s internals) the ability to register
per-`Environment` cleanup work.

We may want to replace `AtExit` with this API at some point.

This prevents calls back into JS from the shutdown phase.
