OpenHarmony VideoProcessingEngine bindings

Raw FFI bindings to the OpenHarmony VideoProcessingEngine subsystem:

• multimedia/video_processing_engine/video_processing.h (libvideo_processing.so) — color space conversion, HDR vivid metadata generation, and video scaling / detail enhancement. Available since API-level 12.
• multimedia/video_processing_engine/image_processing.h (libimage_processing.so) — color space conversion, HDR composition / decomposition, metadata generation, and detail enhancement for OH_PixelmapNative images. Available since API-level 13.

These two libraries ship in the same SDK subdirectory and share the same syscap (SystemCapability.Multimedia.VideoProcessingEngine), but they are documented under different "kits" (Media Kit and Image Kit respectively) and link against separate shared libraries.

C API references:

• Video processing: https://gitcode.com/openharmony/docs/blob/master/en/application-dev/reference/apis-media-kit/capi-video-processing-h.md
• Image processing: https://gitcode.com/openharmony/docs/blob/master/en/application-dev/reference/apis-image-kit/capi-image-processing-h.md

Features

Pick the desired api-XX feature and one or both of video-processing / image-processing. Enabling no module produces an empty crate (useful for feature composability in the umbrella ohos-sys crate).
