Unexpected keyword arg 'inplace' for torch.nn.SiLU

[athitten]

🐛 Bug

NeMo's StableDiffusion uses SiLU activation in its UNet model. When UNet stage is run with thunder.jit, thunder gives an error:
silu() got an unexpected keyword argument 'inplace'.
Specifically the error is is raised in this line of torch/nn/modules/activation.py although inplace is a valid argument of the op.

I had a chat with @athitten on this one. The SiLu in question is purely internal to the model--we could just functionalize this as a solution.

triage review —

• we can add the inplace argument to the signature and throw a NotImplementedError if it's True for now, that will also provide a more informative error message to tell us if this is actually being used inplace
• we should revisit general inplace operator support with Q3 planning
