[0.1.11] macOS and Linux build again: ImGui's Image kept out of the app's scope; a Windows-only field guarded

- src/backends/unix_sdl3_gpu3.jai (macOS and Linux) brought all of ImGui into the app's scope,
  where ImGui.Image collided with modules/Image_Decode's Image struct: both builds have failed
  since 0.0.8 brought in Image_Decode. It now uses ImGui except Image, with a note to keep that
  when the file is generated again.
- app.record_region (-record-region) was a Windows RECT in the shared App struct, from 0.1.6;
  it and its parsing are Windows only now.
- jai check_targets.jai - linux passes. The macOS check needs a Mac: macOS shares the same
  backend file and App struct, so both breaks applied there too.
