Warn when a non-existent property of an unfinished module.exports
object is being accessed, as that very often indicates the presence
of a hard-to-detect and hard-to-debug problem.

This mechanism is only used if `module.exports` is still a
regular object at the point at which the second, circular `require()`
happens.

The downside is that, temporarily, `module.exports` will have a
prototype other than `Object.prototype`, and that there may
be valid uses of accessing non-existent properties of unfinished
`module.exports` objects.

Performance of circular require calls in general is not
noticeably impacted.

This PR exposes a new embedder-focused API: SetIsolateUpForNode.
It maintains previous behavior for the single-param version of
SetIsolateUpForNode and changes no defaults, but was designed to be
flexible by allowing for embedders to conditionally override all
callbacks and flags set by the previous two-param version of
SetIsolateUpForNode.

Original commit message:

    [api] Fix handle leak when getting Context embedder data

    The `Context::SlowGetAlignedPointerFromEmbedderData()` method returns
    a pointer, so the fact that it allocates handles is not obvious to
    the caller.

    Since this is the slow path anyway, simply add a handle scope inside
    of it.

    The tests are also modified to perform the same check for the
    `Object` equivalent of this method.

Due to how the Environment class is used through the codebase,
there are a lot of includes referencing either env.h or env-inl.h.
This can cause that when any development touches those libraries,
a lot of files have to be recompiled.
This commit attempts to change those includes by forward declarations
when possible to mitigate the issue.
