d: add api.value.type union support

Browse Source 
The union of the values is handled by the backend.
In D, unions can hold classes, structs, etc., so this is more similar
to the C++ api.value.type variant.

* data/skeletons/d.m4, data/skeletons/lalr1.d: Here.
* tests/calc.at, tests/local.at: Test it.
