Use arduino-esp32 2.0.2 for ESP32-S2 (#2452)

* Use arduino-esp32 2.0.2 for ESP32-S2

LittleFS is merged into it.

* Fix filesystem error for ESP32-S2

Use platform of tasmota until upstream released it and
use board_build.flash_mode = qio

* Fix empty disk usage

* Add esp32s2_saola to default_envs

* Remove lorol LITTLEFS for esp32dev, too

* Revert "Remove lorol LITTLEFS for esp32dev, too"

This reverts commit 3586d5eef7.
