build: fix / update sensors (windows) configuration

- SDL_config.h.in: add missing defines SDL_SENSOR_COREMOTION
  and SDL_SENSOR_WINDOWS (configure did set SDL_SENSOR_WINDOWS
  but it never went in SDL_config.h or Makefile.)
- SDL_config.h.cmake: remove duplicated SDL_SENSOR_XXX cmake
  defines.
- autofoo, cmake: check for sensorsapi.h header before enabling
  windows sensors.
