[PyTorch] AOTI: generate reused thread_locals when tensors provably have static shape (#110892)
If a Tensor can be reused and has static shape, we can just cache it across iterations.
This is meant as a quickly shippable overhead reduction for CPU overhead-bound use cases that we can ship without relying on memory planning.
