A few Kobo input tweaks (#4450)

* Fix the Touch input probe on Trilogy devices that depend on the touch_probe_ev_epoch_time quirk (fix #630)
* Expose a "Pageturn button inversion" feature in the Navigation menu (for all devices with keys) (fix #4446)
* Allow ignoring the accelerometer on the Forma (Screen > Ignore accelerometer rotation events; also available from the Gesture Manager) (fix #4451)
* Fix SleepCover handling on the Forma (fix #4457)
* Make isWifiOn a tiny bit more accurate (check the actual WiFi module instead of sdio_wifi_pwr)
* Move all flash related Screen options to the eInk submenu
