gh-79413: Add qualname parameter to dataclass.make_dataclass.

[brass75]

Resolves#79413

Added qualname parameter to dataclasses.make_dataclass in order to allow user to set __qualname__ for the generated class.

The pickle issue mentioned in GH-79413 was resolved by #102104 which added the module argument however that PR did not include allowing the user to set __qualname__ for the generated class. This PR resolves that remaining part of this issue.

There should be no backwards compatibility issues - current code that calls make_dataclass without the qualname parameter will continue to create classes that use the cls_name parameter as the __qualname__ with no changes.
