[PyTorch Mobile] Skip signature check when converting to typed operator handle (#49469)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/49469
In Functions.cpp, there is a call to `typed<...>` that converts to a `TypedOperatorHandle`. This isn't needed at runtime since it's already been exercised during development, and for mobile, there is no possibility of operators or kernels being registered by users (from Python code the way it is possible on server side).
