[CodeCamp2023-287] Add DVCLiveVisBackend

[RangeKing]

Motivation

Add DVCLiveVisBackend

Note:
The latest vesion of dvclive in Python 3.7 is 0.9.0 which doesn't support log_param and log_params.
Therefore, Python version should be 3.8 or higher version to use DVCLiveVisBackend.

Could you help update the usage document in docs/zh_cn/common_usage/visualize_training_log.md and docs/en/common_usage/visualize_training_log.md?

With pleasure.
Now there is a problem. DVC works best in a Git repository and most users run experiments in a OpenMMLab repo. But work_dirs/ is in the .gitignore file. Therefore DVC will give a warning WARNING:dvclive:Error in cache: bad DVC file name 'work_dirs\xxx.dvc' is git-ignored.

How about opening an issue on dvclive?

@zhouzaida I wrote a note in document. Recommend not to set work_dir as work_dirs.
And this PR is almost done.
