feat(crowpanel-35): add Elecrow CrowPanel 3.5" (ESP32-S3, ILI9488 + GT911) touch target

- New crowpanel_35 variant: display, SD, board and target files, plus board JSON
- Portrait mode is drawn rotated 180°; landscape stays at rotation 3
- Share the GT911 touch driver between Wio Tracker L2 and CrowPanel
  (WioTrackerL2Touch.cpp -> src/helpers/input/LgfxGt911Touch.cpp)
- platformio envs, flasher/site entries, release and merge-bin support
- Tests for the CrowPanel SD codec and merge-bin
