Feat/deepx npu detector (#24336)

* feat(deepx): add DEEPX NPU detector and runtime integration.

* feat(deepx): enforce model_format requirement when ppu is enabled and add integrity checks for driver installation

* Update frigate/detectors/plugins/deepx.py

Public method lacks docstring

* Refactor DEEPX detector tests, support SSD and DAMO-YOLO

* feat(deepx): add anchor-free output decoding and corresponding tests

* Add tests and updates for DEEPX detector and refactor DEEPX accelerator code structure.

* fix: enhance model type validation and update documentation for DEEPX detector

* fix: add support for customizable score and NMS thresholds

* refactor: infer YOLO layout from the model, drop per-detector options and the dxrtd placeholder

* fix: keep only the anchor-free PPU verdict, re-read anchor-based each frame

* Update latency data for DEEPX NPU

* Expanding PPU support for DEEPX and set yolo-generic as default.

* enhance scale count resolution logic

* Extend PPU layout handling and YOLOX support to DEEPX detector

* fix: assume the largest PPU anchor table when the .dxnn has no layout

* Improve PPU decoding and introduce strides handling

* Improve PPU scope and fix box format mismatch

* Fix unnamed node issue that breaks traversal

* fix: update object detection model type description to remove outdated architecture
