[CodeCamp #29] Add profiler hook functionality

[BayMaxBHL]

Motivation

Migrate the profiler hook of mmcv to mmengine.

Modification

Migrate the profiler hook of mmcv to mmengine:
Some modifications were made to the comments.
Split out the _parse_on_trace_ready method to make the code more readable.

A simple test file was written with the following features:
profiler hooks are generated with default options.
profiler hooks that use log printing.
profiler hooks saved using json.
Use tensorboard's profiler hook.
