feat(ffmpeg): add support for libavutil common and pixelutils headers

- Add new type AVPixelutilsSadFn for av_pixelutils_sad_fn function pointer
- Implement new array conversion functions for signed integer types (ToInt8Array, ToInt16Array, ToInt32Array)
- Add support for common utility functions from libavutil (AVLog2, AVClipC, AVSatAdd32C, etc.)
- Include libavutil/common.h and libavutil/pixelutils.h in generator configuration
- Add primType mappings for int8_t to enable proper code generation
