Some actions may be performed when scrcpy exits, currently:

They are performed from a separate process so that they can be executed even when scrcpy-server is killed (e.g. if the device is unplugged).

The clean up actions to perform were configured when scrcpy started. Given that there is no method to read the current "power mode" in Android, and that "turn screen off" can be applied at any time using an scrcpy shortcut, there was no way to determine if "power mode" had to be restored on exit. Therefore, it was always restored to "normal", even when not necessary.

However, setting the "power mode" is quite fragile on some devices, and may cause some issues, so it is preferable to call it only when necessary (when "turn screen off" has actually been called).

For that purpose, make the scrcpy-server main process and the clean up process communicate the actions to perform over the stdout/stdin, so that they can be changed dynamically. In particular, when the power mode is changed at runtime, notify the clean up process.
