[static_runtime] fix num args for to_copy (#56441)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/56441
Since aten::to is overloaded, match schema to replace it with static_runtime::to_copy
Test Plan:

I verified that all of the aten::to matches, for the local, local_ro, and remote_ro nets in opt and dev mode.
Only 2 of calls are replaced because the other 155 have either the input or the ouput of the op returned as an external output. This is a similar case for the other instances of aten::to in the local and local_ro nets.
