[Feature] Add tools/analysis_tools/print_config.py

[i-aki-y]

Add a print_config.py into 1.x branch

Motivation

close #1535

Modification

Add a new script tools/misc/print_config.py
The code was borrowed from the other open-mmlab project.
ex. https://github.com/open-mmlab/mmclassification/blob/1.x/tools/misc/print_config.py

BC-breaking (Optional)

This works in 1.x branch and does not in < 1.x because the Config and DictAction are imported from the mmengine instead of mmcv.
