[Transformation][CPU]Strided_slice branches concatination fused to single gather

[chenhu-wang]

Details:

• There is single source consumed by multiple strided_slice nodes, the sliced output then are concatenated. This pattern could be replaced by single gather node with index collected from slice. This could dramatically reduce node number and improve compile time/tput and reduce used memory

CI Doctor — Merge Queue failure on this PR

Pipeline: Windows (VS 2022, Python 3.11, Release)
Failure: JS API E2E Electron cleanup fails on Windows - Permission denied removing locked electron.exe/dll
Automatic restart: ✅ Re-run of failed jobs requested (reason: Flaky Windows test cleanup - electron.exe file locks prevent rm -rf; a plain restart is likely to succeed)

Possible remedy

1. Re-run is already triggered — this failure is unrelated to your PR changes (CPU plugin transformation).
2. If it fails again, the JS API team should replace rm -rf with fs.rm({ recursive: true, force: true, maxRetries: 5 }) in the mocha 'after all' cleanup hook.
3. Alternatively, add an explicit taskkill /F /IM electron.exe step before cleanup on Windows runners.
4. A dedicated tracking issue should be filed — this pattern has recurred 11 times since 2026-07-09.

What happened

The JS API E2E test's cleanup hook ran rm -rf demo-electron-app-project after a successful Electron integration test, but Windows file locks on electron.exe, d3dcompiler_47.dll, libEGL.dll, and libGLESv2.dll caused Permission denied errors. This is a known flaky infrastructure issue in the Windows CI that has been seen 3 times in the last 12 hours alone (runs 29564867992, 29568028549, 29573015584).
