Fail fast when dynamo attempts to add unspecialized int/float as additional graph inputs (#96786)
Summary:
Verified the changes to catch unspecialized int/floats being added as additional graph in D44037548 prior to RP(https://github.com/pytorch/pytorch/pull/95621).
However, with #95621 the issue to be solved originally is no longer valid because int & float in `forward` will always be specialized in export. This RP is to add the assertion anyway *(though not be hit unless there is a regression)* to immediately catch the attempt to add unspecialized int/float to additional graphargs
Test Plan:
Example of the error message would look like:
```
Dynamo attempts to add additional input: value=9.999999747378752e-06, source=NNModuleSource(inner=AttrSource(base=NNModuleSource(inner=AttrSource(base=LocalInputSource(local_name='self', pos=0), member='torch_module')), member='eps'))
```
Passed all export tests
```
