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.
