Removed direct doc formatting
Fixes #76034
This does not make python remove all `__doc__` because in some places `__doc__` is assigned to a string.
Example:
https://github.com/pytorch/pytorch/blob/04b3313379712098183dfe5bea002a5e43b5af48/torch/nn/modules/conv.py#L174-L233
Since there are quite a few of these, I will add all of them together in this PR later. (Basically still a lot of docstring will persist even with `-OO` enabled.)
