ns for fx: clean up convtranspose mappings
Summary:
Fixes a couple of problems with `ConvTranspose` in NS mappings:
1. deletes the dynamic versions, as they do not work yet
2. deletes `ConvTranspose3d`, as it's not swapped yet in the quantization workflow
3. removes a duplicate set
Test plan:
```
python test/test_quantization.py -k FXGraphMatcher
python test/test_quantization.py -k FXNumericSuite
```
