Frozen dataclass can be hashable

```py
from dataclasses import dataclass

@dataclass(frozen=True)
class Data:
a: int
b: int

data1 = Data(1,2)
print(data1)

dict = {data1: "firstdata"}

print(dict)
```
For now, we need a different branch to handle this scenario, and as we can assume this one is also `_ast.Call` object
we need to add a new branch for _ast.Call for frozen type which can be hashable
