[Inductor] Support deterministic parallel reduction in CPP backend

[jgong5]

CPP backend uses OMP to do parallel reduction which cannot guarantee a deterministic reduction order and might produce different run-to-run result while determinism is important to ease the debugging. We should replace omp parallel reduction with deterministic parallel reduction.

Relevant issue/PR: #93542, #87259
