Fixes#130087
This patch tries to provide a built-in id function implementation for TensorVariable when the id function is called on tensors like module parameters. The id function call on intermediate tensors is not supported.

Fixes https://github.com/pytorch/pytorch/issues/130750.
Repro of lazy/eager `map` discrepancy without `islice`:
```python
def fn(a, b):
y = 1
def f(x):
nonlocal y
y += 1
return x
l = list(zip([a, b], map(f, [1, 2, 3, 4])))
return a + y
```
The major change is that we implement `MapVariable` and `ZipVariable` based on `IteratorVariable`. Before, `map` and `zip` were being traced by immediately unpacking the result as a `TupleVariable`, which is wrong in cases such as the example above.
`MapVariable`s are not allowed to be unpacked while `ZipVariable`s can only be unpacked if all of its iterables can also be unpacked.
We also add new `[has_]force_unpack_var_sequence` methods to `VariableTracker` for the case where it is safe to unpack the entire sequence lazily, e.g., when building a list from a map (i.e. `list(map(f, ...))`).

Before the pr, we have a graph break for `callable(nn_module)`:
```python
class M(nn.Module):
def forward(self, x):
return x.sin()
def f(m):
return callable(m)
res = torch.compile(f, fullgraph=True)(M())
```
```
