This removes crossbuild-specific code from the meson scripts and will
simplify dependency upgrades.

-/**
- * 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).
