Use c10::ArrayRef instead of std::vector for the jit::unpickle's tensor_table. (#54428)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/54428
Using c10::ArrayRef as the parameter type makes the API more flexible and allows the caller to leverage small-buffer optimizations (e.g. c10::SmallVector, std::array) for performance critical cases.
Test Plan: No behavioral changes. Run the existing unit and integration tests.
