skip detectron2_fcos_r_50_fpn in dynamic shape test (#120697)
Summary:
As reported in https://github.com/pytorch/pytorch/issues/119434, `detectron2_fcos_r_50_fpn` failed with dynamic shape testing, we propose to skip the dynamic batch size testing of this model in this PR.
* Error msg is
```
File "/home/jiayisun/pytorch/benchmarks/dynamo/common.py", line 3877, in run
assert marked, f"nothing in example_inputs had a dim with {batch_size}"
AssertionError: nothing in example_inputs had a dim with 4
```
* Root Cause is
Benchmark code will only annotate the inputs' dim as dynamic when its size equals to batch size https://github.com/pytorch/pytorch/blob/c617e7b4076a5f968f5827040a07b013e45cd0c6/benchmarks/dynamo/common.py#L3867-L3871. If it fails to find any dim equals to batch size, above error throws.
However, the inputs of `detectron2_fcos_r_50_fpn` are as follows:
```
([{'file_name': '/home/jiayisun/benchmark/torchbenchmark/data/.data/coco2017-minimal/coco/val2017/000000001268.jpg', 'height': 427, 'width': 640, 'image_id': 1268, 'image': tensor([[[147., 124., 82., ..., 3., 4., 5.],
[125., 104., 65., ..., 3., 3., 4.],
[ 87., 68., 34., ..., 2., 2., 2.],
...,
[ 47., 45., 41., ..., 45., 45., 45.],
[ 46., 44., 40., ..., 44., 45., 46.],
[ 46., 44., 40., ..., 43., 45., 46.]],
[[154., 129., 84., ..., 3., 4., 5.],
[133., 110., 69., ..., 3., 3., 4.],
[ 95., 76., 43., ..., 2., 2., 2.],
...,
[ 44., 42., 38., ..., 34., 37., 39.],
[ 43., 41., 37., ..., 35., 39., 41.],
[ 43., 41., 37., ..., 35., 40., 43.]],
[[171., 140., 85., ..., 3., 4., 5.],
[147., 120., 71., ..., 3., 3., 4.],
[103., 83., 47., ..., 2., 2., 2.],
...,
[ 46., 44., 40., ..., 16., 20., 22.],
[ 45., 43., 39., ..., 17., 22., 26.],
[ 45., 43., 39., ..., 18., 24., 28.]]])}, ... ],)
```
None of the inputs' dim will equal to input batch size, so I think we may need to skip the dynamic batch size testing for this model.
