`Image::from_buffer`'s public signature changes if debug assertions are enabled

[rparrett]

Stumbled on this review comment that came a bit too late after a merge.

This is a public API, so this will break bevy plugins using it if the "wrong" build configuration is enabled by the user.

tracing allows attaching this information to a Span instead, which is a better way to do this (the warn_once! will include the span's fields).
