Support the `ExitStack` context manager (or a simplified version)
Labels: triaged, oncall: pt2, module: dynamo

### 🐛 Describe the bug

I'm trying to compile a piece of code with `fullgraph=True` that uses multiple context managers.

I saw that https://github.com/pytorch/pytorch/pull/98725 should support this sort of behaviour (cc: @yanboliang as author)

https://github.com/Lightning-AI/lightning/pull/18557 includes some real pieces of code that show this pattern

```python
from contextlib import ExitStack

class A:
    def __enter__(self): pass
    def __exit__(self, exc_type, exc_val, exc_tb): pass

class B:
    def __enter__(self): pass
    def __exit__(self, exc_type, exc_val, exc_tb): pass


def init_context():
    stack = ExitStack()
    stack.enter_context(A())
    stack.enter_context(B())
    return stack


def fn():
    with init_context():
        return 1 + 2

import torch
fn = torch.compile(fn, fullgraph=True)
out = fn()
``` 

However, this fails with

```python

    stack.enter_context(A())
```

I also tried my own simplified implementation:

```python
class ExitStack:
    def __init__(self, context_managers) -> None:
        self._context_managers = context_managers

    def __enter__(self):
        for ctx_manager in self._context_managers:
            ctx_manager.__enter__()

    def __exit__(self, exc_type, exc_value, traceback):
        for ctx_manager in reversed(self._context_managers):
            ctx_manager.__exit__(exc_type, exc_value, traceback)

class A:
    def __enter__(self): pass
    def __exit__(self, exc_type, exc_val, exc_tb): pass

class B:
    def __enter__(self): pass
    def __exit__(self, exc_type, exc_val, exc_tb): pass


def init_context():
    stack = ExitStack([A(), B()])
    return stack


def fn():
    with init_context():
        return 1 + 2

import torch
fn = torch.compile(fn, fullgraph=True)
out = fn()
```

Which fails with

```python

```
The test suite includes tests for similar classes: https://github.com/yanboliang/pytorch/blob/main/test/dynamo/test_ctx_manager.py so I would expect that supporting this basic version is feasible.
