[issue44695] asdict use deep copy to dataclass instances

[Itay azolay]

New submission from Itay azolay :

Hi, 
I noticed that 'asdict' use 'deepcopy' on all fields of the dataclass 
recursively. 
I believe this behavior can become optional with an argument, and shouldn't be 
decided for the user as the deepcopy takes significant amount of cpu and can 
have unexpected consequences on memory.

I don't mind taking this PR if you agree. 
Thanks
