Renamed ShowTextInput/HideTextInput to ShowScreenKeyboard/HideScreenKeyboard on Android

This better reflects the actual implementation and makes SDL_HINT_ENABLE_SCREEN_KEYBOARD work on Android.

Fixes https://github.com/libsdl-org/SDL/issues/8652

(cherry picked from commit 014a63b4b5b94ce50f329eddb345f5434654305b)
