The point of bpo-40369 issue seems to be to provide vectorcall to the `GenericAliasType`, means vectorcall for `Queue[int]`

However, my idea is to add vectorcall to gaobject, like this:

```
d = dict[int]
d(a=1, b=2) <-- vectorcall
```

The idea came from my desire to implement different subclasses of a type when implementing some kind of factory model：

```
class ChildClassBuilder:
    ...

    def set_type(self, t: Type):
        self.t = t

    def build():
        instance = self.t()
        ...
        return instance
```

In the case of high type-hint coverage, the `self.t` is often a gaobject.

Benchmark example：
```
def test():
    d = dict[int]
    for _ in range(1000000):
        d(a=1, b=2)
```
