Optimize log print by using html format

Browse Source 
Summary:
See facebook/yoga#453. Optimizes the node log print by generating some enum text via ```enum.py``` and moving printing to new functions to reduce boilerplate code.

Changes the log output to format the nodes in html to be able to copy paste it  into browsers for quick debugging.

Hides all default values.
Closes https://github.com/facebook/yoga/pull/479
