[JIT] remove builtin interpolate functions (#34514)
Summary:
`torch.nn.functional.interpolate` was written as a builtin op when we scripted the standard library, because it has four possible overloads. As a result, whenever we make a change to `interpolate`, we need to make changes in two places, and it also makes it impossible to optimize the interpolate op. The builtin is tech debt.
I talked with ailzhang, and the symbolic script changes are good to remove (i guess that makes a third place we needed to re-implement interpolate).
I'm trying to get rid of unneccessary builtin operators because we're standardizing mobile bytecode soon, so we should try to get this landed as soon as possible.
