bug#45668: 28.0.50; image-mode does not respect EXIF orientation

[Dima Kogan]

Hi. I'm opening an image with an EXIF orientation tag, and emacs does
not respect this orientation tag.

This was fixed earlier in

  https://debbugs.gnu.org/cgi/bugreport.cgi?bug=22591

I'm wondering if the autoconf switch is implemented improperly. I'm
seeing the relevant code in image.c blocked in

  #ifdef HAVE_MAGICKAUTOORIENTIMAGE

but it's not obvious to me that the autoconf logic exists to ever turn
this on. I'm not an expert in autoconf. Can somebody please check?

Thanks!
