[Torch] Add decomposition of RepeatInterleaveSelfInt Op (#3075)
Decomposition RepeatInterleaveSelfInt with following ops:
```python

def my_repeat_interleave(input, repeats, dim=None):
    if dim is None:
        # Flatten the input and then repeat
        return input.flatten().unsqueeze(-1).tile((1, repeats)).flatten()
    else:
        # Calculate the shape after repeat
        expanded_shape = list(input.shape)
        expanded_shape[dim] *= repeats
        # Repeat the tensor along the specified dimension
        repeat_shape = [1] * (input.dim() + 1)
        repeat_shape[dim + 1] = repeats
        input = input.unsqueeze(-1)

        # Tile and then reshape
        tiled = torch.tile(input, repeat_shape)
        # Rearrange and reshape
        repeated = tiled.reshape(*expanded_shape)
    return repeated

```

I passed the tests of stablehlo and linalg. When testing onnx, strange
things happened.
In torch-mlir's CI **torch_nightly** and my own
environment(torch==2.4.0.dev20240318+cpu), it can **pass the pass**.
In torch-mlir's CI  **torch_stable**, it **failed**.
The test case is `RepeatInterleaveSelfIntNoDimModule_basic`, the result
shape should be [120].
```python
class RepeatInterleaveSelfIntNoDimModule(torch.nn.Module):

    def __init__(self):
        super().__init__()

    @export
    @annotate_args([
        None,
        ([3, 4, 5], torch.float32, True),
    ])
    def forward(self, x):
        return x.repeat_interleave(2)


@register_test_case(module_factory=lambda: RepeatInterleaveSelfIntNoDimModule())
def RepeatInterleaveSelfIntNoDimModule_basic(module, tu: TestUtils):
    module.forward(tu.rand(3, 4, 5))
```
The error log is as follows:
```
  Unexpected outcome summary: (onnx)
  
  ****** Failed tests - 1 tests

          @ trace item #0 - call to "forward"

          ERROR: shape (torch.Size([6, 4, 5])) is not equal to golden shape (torch.Size([120]))
```

@rsuderman 
Would you please help me check what's wrong with my PR? Thanks a lot.
