[TensorExpr] Fix printing of Bool dtype. (#59328)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/59328
Before the change we printed:
```
aten_eq[0] = decltype(::c10::impl::ScalarTypeToCPPType< ::c10::ScalarType::Bool>::t)((targ_0[0])==(targ_1[0]) ? 1 : 0);
```
After the change we print:
```
aten_eq[0] = bool((targ_0[0])==(targ_1[0]) ? 1 : 0);
```
