This PR introduces the VC8000NanoE software stack needed on top of STM32N6 VENC hardware peripheral in order to enable H264 hardware video compression.
This code comes from STM32CubeN6 firmware code located here: https://github.com/STMicroelectronics/STM32CubeN6/tree/main/Middlewares/Third_Party/VideoEncoder/source
Some changes have been made to comply with Zephyr build system and Zephyr kernel defines.
The debug trace system has been adapted and some trace points fixed.
Debug traces are enabled by setting CONFIG_VC8000NANOE_LOG_LEVEL >= LOG_LEVEL_DEBUG.
