Introducing TY-NNP backend with end2end TensorIR integration

Development RFC

@mbs-octoml Hi~ Many thanks for your reply! Here are several questions of me:

  1. What does call_lowered mean? Does it mean we can put PrimFuncs and relay functions into the same IRModule and make calls to each other now?

  2. For the VirtualDevice, it would be the interface to keep all information we required across relay-tir boundary, is my understanding right? This would be a closed set (including device, mem scope, etc) or allow thirdparty extensions?

  3. Just out of my curiosity, what is the difference between ongoing Relax and current machanism described?
