As part of the unified IR refactor. This PR refactors the target codegen to use IRModule containing tir::PrimFuncs. In order to break the refactor into several steps without breaking the codebase, we built an conversion pass to convert Array<LoweredFunc> into IRModule. The follow-up refactors will gradually move the passes covered by IRModule up until we cover all the passes. Then we can remove the additional redundant concepts such as LoweredFunc.

TIR is the new namespace for low-level IR for tensor-level optimizations and loop transformations. This PR establishes the namespace and files. - lowered_func.h,buffer.h,data_layout.h -> tir/buffer.h,tir/data_layout.h,tir/lowered_func.h - ir.h -> tir/expr.h, tir/stmt.h - ir_functor_ext.h -> tir/expr_functor.h, tir/stmt_functor.h

Spread the arithmetic.h into several components and move into arith subfolder. The arith namespace will be used for arithmetic expression pattern detections and simplifications.

* [REFACTOR][IR] tvm::Expr -> PrimExpr(Primitive Expr) As part of unified IR, we will need to unify relay::Expr and the current tvm::Expr under the same base type. From the techinical point of view. tvm::Expr is a "primitive" expression that only contains POD types and handles and does not do life-cycle management. This PR renames Expr->PrimExpr to clarify that. We will send a subsequent PR to introduce the base expr class. * Remove legacy VarExpr and ExprHash/Equal

* [REFACTOR][NODE][RUNTIME] Move Node to the new Object protocol. This PR removes the original node system, and make node as a subclass of Object. This is a major refactor towards a better unified runtime object system. List of changes in the refactor: - We now hide data_ field, use Downcast explicitly to get a sub-class object. - Removed the node system FFI in python. - Removed the node C API, instead use PackedFunc for list and get attrs. - Change relay::Op::set_attr_type_key(attr_key_name) to relay::Op::set_attr_type<AttrType>(). - This change was necessary because of the new Object registration mechanism. - Subsequent changes to the op registrations - The change revealed a few previous problems that is now fixed. - Patched up a few missing node type registration. - Now we will raise an error if we register object that is not registered. - The original node.h and container.h are kept in the same location. - Calling convention: kObjectHandle now equals the old kNodeHandle, kNodeHandle is removed. - IRFunctor now dispatches on ObjectRef. - Update to the new type checking API: is_type, derived_from are replaced by IsInstance. - Removed .hash member function, instead use C++ convention hasher functors. * Address review comments
