Prerequisite

• I have searched Issues and Discussions but cannot get the expected help.
• The bug has not been fixed in the latest version(https://github.com/open-mmlab/mmcv).

Environment

torch:2.1.0
mmcv:2.1.0
mmdet:3.2.0
mmengine:0.10.5
mmdet3d:1.4.0

Reproduces the problem - code sample

from mmcv.parallel import MMDataParallel, MMDistributedDataParallel
from mmcv.runner import (
HOOKS,
DistSamplerSeedHook,
EpochBasedRunner,
Fp16OptimizerHook,
OptimizerHook,
build_optimizer,
build_runner,
get_dist_info,
)

已知mmcv升级到2.0之后以上内容会移除，请问这些内容移动到哪里了？以及已经在mmengine中找到了MMDistributedDataParallel但没有找到MMDataParallel，请问MMDataParallel在哪里
