Reduce string duplication in enum debug output operators.

This change is of course more significant in the context of a minimal WebGL build, where the exe can be as little as 50 kB -- there 4 kB is almost 10% of the size.

GL: add ES-only TextureFormat::BGRA[8]. And clarify their purpose. This was an accidental ommision, as there's no need for such a thing on desktop.
