[REFACTOR][PY][API-CHANGE] establish tvm.ir, migrate corresponding files (#4862)
* [REFACTOR][PY][API-CHANGE] establish tvm.ir, migrate corresponding relay files.
This PR establishes tvm.ir and migrates the corresponding relay
files into the new folder.
API Change:
- relay.Module -> tvm.IRModule
* Update with ADT
* Migrate transform
* address comments
* Migrate module
* Migrate json_compact
* Migrate attrs
* Move LoweredFunc to stmt temporarily
* temp migrate container
* Finish migrate container
