add print_config.py to the tools

[IncludeMathH]

#1545

Motivation

In previous versions of mmocr, as well as in projects such as mmdetection, there was a program (tools/misc/print_config.py) that could print out the complete configuration file directly. There is one reference in MMDetection which can almost be directly applied to MMOCR, so I just add it back.

Modification

Add print_config.py back to tools/anaylsis_tools.

BC-breaking (Optional)

Use cases (Optional)

It is a useful tool that can print out the complete configuration file directly.

Thanks for your contribution! The file didn't pass our lint test due to the lack of the newline at the end of the file. Could you do a quick fix on it?
