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.
