Replace the separate cpp20_nightly.yml with a dedicated '0 2 * * *' schedule in ubuntu_22, ubuntu_24 and windows_vs2022_release. On that schedule only Build_CPP20 runs (Build and its dependents are skipped); Build_CPP20 no longer runs in pre-commit. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

🟡 Changes recommended
The workflow builds the wrong ref when a target branch is requested, prevents nightly Windows cache refreshes, and omits C++20 validation when draft PRs become ready for review.

What changed in this PR
Moves OpenVINO’s non-blocking C++20 compile checks out of regular validation workflows into a dedicated nightly workflow, reducing runner use without changing required checks.
Changes:
- Schedules Ubuntu 22.04, Ubuntu 24.04, and Windows VS2022 Release builds daily at 00:00 UTC.
- Adds manual dispatch and path-filtered PR triggers for C++20 workflow changes.
- Reuses existing build workflows and preserves their CMake options and non-blocking behavior.
