Daniel Chao 0035199176 Improve partial-evaluation when amending null parents (#1836)
GraalVM's partial evaulator can't handle recursive calls into the same
node.

The current implementation around evaluating `VmNull` as a parent causes
the partial evaluator to bail out, leaving Pkl stuck in interpreter
mode.

This rewrites the various object literals to add individual
specializations for each type of default value we can see from a VmNull
parent.

Also:
* Fix `isTypeObjectClass` impl
* Fix bug when amending with generator object literal node with object params
