Original commit message:

    Add an `v8::ArrayBuffer::WasDetached` method to the C++ API

    V8's C++ API does not give a way to tell whether an ArrayBuffer has
    been detached from the `v8::ArrayBuffer` class. In fact, as far as can
    be told from the C++ API without running JS code, detached
    ArrayBuffers behave the same as zero-sized ArrayBuffers and there is
    no way to observe the difference. However, this difference can be
    observed in JS because constructing a TypedArray from a detached
    ArrayBuffer will throw.

    This change adds a `WasDetached` method to the `v8::ArrayBuffer` class
    to give embedders access to this information without having to run JS
    code.
