Keep the display mode daemon process alive

On Android 14, a separate process was spawn on every display mode
request (to turn the screen off or on).

But starting a java process takes time (a few hundred milliseconds),
causing a noticeable latency between the request to turn the screen off
(MOD+o) or on (MOD+Shift+o) and the actual power mode change.

To minimize this latency, keep the process alive between requests, so
that only the first one will have to spawn the process.

It would be possible to spawn the process in advance, so that even the
first request would be immediate, but any problem would impact all
Android 14 users even without using the "turn screen off" feature.

+ * On Android 14, the methods used to turn the device screen off have been moved from SurfaceControl (in framework.jar) to DisplayControl (a system
+ * server class). As a consequence, they could not be called directly. See {@url https://github.com/Genymobile/scrcpy/issues/3927}.
+ * <p>
+ * Instead, run a separate process with a different classpath and LD_PRELOAD just to set the display power mode. The scrcpy server can request to
+ * this process to set the display mode by writing the mode (a single byte, the value of one of the SurfaceControl.POWER_MODE_* constants,
+ * typically 0=off, 2=on) to the process stdin. In return, it receives the status of the request (0=ok, 1=error) on the process stdout.
+ * <p>
+ * This separate process is started on the first display mode request.
+ * <p>
+ * Since the client must not block, and calling/joining a process is blocking (this specific one takes a few hundred milliseconds to complete),
+ * this class uses an internal thread to execute the requests asynchronously, and serialize them (so that two successive requests are guaranteed to
+ * be executed in order). In addition, it only executes the last pending request (setting power mode to value X then to value Y is equivalent to
+ * just setting it to value Y).
