Previously the printer does not respect the difference between tir.Var and
tir.SizeVar, which means SizeVar info will be lost during roundtripping, which
is not ideal when dealing with dynamic shape workloads, where SizeVar provides
additional bound information to the arithmetic analyzer.
This PR extends Var printing to support SizeVar:
```python
>>> a = tir.SizeVar("a", "int32")
>>> print(a.script(verbose_expr=True))
a = T.int32(size_var=True)
a
```
