A variable node in the IR.
A variable is uniquely identified by its address.
Each variable is only bound once in the following nodes:

String tvm::tir::VarNode::name_hint |
The hint to the variable name.
Type tvm::tir::VarNode::type_annotation |
type annotation of the variable.
It is an optional field that provides a refined type of the variable than dtype.
