What does this pull request change?

This PR drastically change the way IO routing bits setting generation flow:

• Old way is to model all the routable resources in device dedicated config mapping file (each device has different resources), and C code read those information and do the routing in C code

• New way is to use Python script model the circuitry/block-diagram of routable resouces, during bitstream generation, C code will just need to give enough information to Python script for example: start node, essential node, end node etc, the Python will do the routing based on the model

Which part of the code base require a change

• Library:
• Plug-in:
• Engine
• Documentation
• Regression tests
• Continous Integration (CI) scripts

Impact of the pull request

• Require a change on Quality of Results (QoR)
• Break back-compatibility. If so, please list who may be influenced.
