Simplify our code by using std::cout from ESP32-S3 runtime environment.

The runtime environment bundled within the [GCC Toolchain for Espressif ESP32-S3 Xtensa MCUs](https://registry.platformio.org/tools/espressif/toolchain-xtensa-esp32s3) apparently already maps `std::cout` to serial interface.
No need to maintain our own version of it.
