Supersedes #24447 with a clean release pick from #24400.

Adds the portable antialiased bicubic kernel, edge-verifier exception, registration/build wiring, regression tests and matching Arm recipe/documentation updates from the source PR.

Changes exactly the 15 source PR paths.

Scope and landing order

Land after #24493 in the verified landing order.

This branch starts directly at release/1.6 commit dfb78b9ecd933a5fee33ebc94f69ed4b71cbb1e7. Its GitHub diff contains 15 files for this pick; it does not carry duplicate #24298 history or the excluded unmerged QNN work. Dependencies are documented here rather than embedded as other cherry-pick commits.

Verification

All changed Python files compile and pass Ruff F821 checks. All seven replacements merge cleanly in the documented sequence, including simulated squash merges. No QNN files are changed.

Native CUDA, OpenVINO and portable C++ suites were not run locally on this macOS host; PR CI remains required before landing.

Prepared with OpenAI Codex.

Cherry-pick #24400 without inherited backend fixes or QNN changes.
