Move the CUDA/CPU/XPU torch stack from 2.13.0 to 2.14.0 to pick up the stable-ABI StableIValue -> std::string host-memory-leak fix (pytorch/pytorch#190493). That fix only exists in the torch 2.14 line and was never backported to 2.13 (no v2.13.1; release/2.13 stopped at the 2.13.0 GA cut), so a torch patch bump cannot resolve it. Refs #52089, #50870.

DRAFT: blocked on torch 2.14.0 GA (currently v2.14.0-rc5). torchaudio 2.12.0 is provisional (no tag yet); compiled test lockfiles (requirements/test/*.txt), docker image digests, and the ROCm stack (separate cadence) still need updating once GA wheels are published.

Essential Elements of an Effective PR Description Checklist
  • The purpose of the PR, such as "Fix some issue (link existing issues this PR will resolve)".
  • The test plan, such as providing test command.
  • The test results, such as pasting the results comparison before and after, or e2e results
  • (Optional) The necessary documentation update, such as updating supported_models.md and examples for a new model.

Closing as a duplicate of #52183, which already does this bump more completely.
