hwcodec, only process that start ipc server start check process (#8325)

check process send config to ipc server, other process get config from ipc server. Process will save config to toml, and the toml will be used if the config is none.

when start check process: ipc server process start or option changed
from disable to enable

when get config: main window start or option changed from disable to
enable, start_video_audio_threads.

Only windows implements signature, which is used to mark whether the gpu software and hardware information changes. After reboot, the signature doesn't change. https://asawicki.info/news_1773_how_to_programmatically_check_graphics_driver_version, use dxgi way to get software version, it's not consistent with the visible driver version, after updating intel driver with small version change, the signature doesn't change. Linux doesn't use toml file.
