[Static Runtime] Add perf metrics for number of managed tensors & unmanaged values (#64992) Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/64992 This change lets Static Runtime print out number of managed tensors & unmanaged values as performance metrics during profile runs. We will use /enhance these metrics to guide the effort of managing output tensors. Test Plan: Confirmed that a profile run prints out the added metric values on inline_cvr nets: ``` (inline_cvr/local) ... Total number of managed tensors: 2754 Total number of unmanaged values: 3240 ... (inline_cvr/local_ro) Total number of managed tensors: 1554 Total number of unmanaged values: 2966 ... (inline_cvr/remote_ro) Total number of managed tensors: 1439 Total number of unmanaged values: 28 ... ``` Reviewed By: hlu1 Differential Revision: D30926617 fbshipit-source-id: b86e071003ac941b9663db103eaa7c614466b4e0
