The special-case code for handling SUPPORTED_NODES was producing a guard that looked like:
```
"G['torch'].utils._pytree.SUPPORTED_NODES[<class '__main__.CausalLMOutputWithPast'>].type"
```
resulting in a eval error trying to evaluate the guard.
This change adds a new source type (`ClassSource`) which is given a class type (in this case `CausalLMOutputWithPast`) and attempts to fetch it from its defining module. It then uses that to build the `SUPPORTED_NODES` guards instead of referring to the type directly.
Also added a unit test which fails before this change and passes after.

When building guards which went through a property we were analyzing the property using getattr_static but the guard wasn't built using getattr_static so if the property was "unusual" it generated misbehaved code which referenced a non-existent `__closure__` field.
Fixes#118786
Note that after this change some of the referenced tests are still failing with a different error - but getting further.
