This issue is to track progress for TVMScript Unified Printer

Part 1: Doc

In each step we will introduce several Doc subclasses and implement the corresponding part in PythonDocPrinter.

• LiteralDoc (together with Doc, DocPrinter base class and PythonDocPrinter) ([TVMScript] Doc Base Class & DocPrinter Scaffolding #11971)
• ExprDoc ([TVMScript] ExprDoc #12048, [TVMScript] Printer: add boolean operators to OperationDoc #12518)

• Operator Associativity ([TVMScript] Python Expression Precedence #12148)

Part 2: Core infra

The following items can be worked on in parallel with items from part 1.

• ObjectPath ([TVMScript] Add ObjectPath class #11977)
