If we clear to transparent black, we're not forcing the pass to be constructed. Change the entity pass API so that we can tell the difference between clearing transparent black and not having a clear color.

In https://github.com/flutter/flutter/issues/139571 , the app is creating a layer that is clearing to a transparent color, which is getting skipped. That invalid texture is fed into a blend which produces either black or magenta error texture.
