Yevhen Babiichuk (DustDFG) af6d260c17 Don't include core/io/image.h in core/os/os.h
`core/os/os.h` doesn't use `core/io/image.h`. It just brings
transitive dependencies. Lots of dependencies because `core/os/os.h`
is transitively included in almost every file of godot

Also added `core/io/image.h` into files^1 where `Ref<Image>` and `core/os/os.h`
were used to prevent obscure errors involving `Ref<Image>`

^1 except those which include `core/io/image_loader.h` or `core/io/image.h` by
corresponding .h file with the same name
