Add support for complex filter value var handle adaptation

It is sometimes necessary to apply a carrier transform on a VarHandle that is expressed in more than just a pair of unary function (e.g. from A->B and B->A). Sometimes the transform needs to act on some bit of external state.

It would be nice if MemoryHandles::filterValue would be enhanced to accept all functions of the kind:

(C... A) ->B
(C... B) -> A

So that the resulting VarHandle will apply carrier transform from A to B and will also add extra coordinate types (C...) which can be used by the transform filters.
