feat(ui-lvgl): GPS on three tabs -- Sky, Signal, Details

Browse Source 
Each tab a screenful: the sky plot beside the fix; the bars with a fixed
dB-Hz scale and the constellations; and Details with whatever else the
receiver reports (correction, locator, course, DOPs with their rating,
signal averages, NMEA counts). Sim: sim_open("gps").
