bpo-33134: dataclasses: use function dispatch table for hash, instead of a string lookup which then is tested with if tests. (GH-6222)

* Change _hash_action to be a function table lookup, instead of a list
of strings which is then tested with if statements.

Trivial dataclass cleanups: (GH-6218)
...
- When adding a single element to a list, use .append() instead of
+= and creating a new list.
- For consistency, import the copy module, instead of just deepcopy. This
leaves only a module at the class level, instead of a function.
- Improve some comments.
- Improve some whitespace.
- Use tuples instead of lists.
- Simplify a test.

bpo-32953: Dataclasses: frozen should not be inherited for non-dataclass derived classes ( #6147 )
...
If a non-dataclass derives from a frozen dataclass, allow attributes to be set.
Require either all of the dataclasses in a class hierarchy to be frozen, or all non-frozen.
Store `@dataclass` parameters on the class object under `__dataclass_params__`. This is needed to detect frozen base classes.

unsafe_hash=False is now the default. It is the same behavior as the old hash=None parameter. unsafe_hash=True will try to add __hash__. If it already exists, TypeError is raised.

bpo-32513: Make it easier to override dunders in dataclasses. (GH-5366)
...
Class authors no longer need to specify repr=False if they want to provide a custom __repr__ for dataclasses. The same thing applies for the other dunder methods that the dataclass decorator adds. If dataclass finds that a dunder methods is defined in the class, it will not overwrite it.
