zeshengzong 5b326d6b61 Add gdb print methods support same as pytorch-lldb (#140935) ...

`pytorch-lldb` support pretty printing size and key_set of tensor via #97101

Add same pretty printing for gdb debugging.

**Test Result**

```bash
$ gdb python
(gdb) break at::native::negative
(gdb) r
>>> import torch
>>> t = torch.tensor([1, 2, 3, 4], dtype=torch.float64)
>>> t.negative()
Thread 1 "python" hit Breakpoint 1, at::native::negative (self=...) at /home/zong/code/pytorch/aten/src/ATen/native/UnaryOps.cpp:854
854	Tensor negative(const Tensor& self) { return self.neg(); }
```

**Before**
```bash
(gdb) p self.key_set()
$2 = {repr_ = 1271310352385}

(gdb) p self.sizes()
$3 = {Data = 0x9cb488, Length = 1}

```

**After**
```bash
(gdb) torch-int-array-ref-repr self.sizes()
[4]
(gdb) torch-dispatch-keyset-repr self.key_set()
DispatchKeySet(CPU, ADInplaceOrView, AutogradCPU, AutocastCPU)
```

```bash
$ lintrunner
```
