New API for static logging

[JakeWharton]

I'm thinking that you append a composable function to a composition local, with an option of choosing stderr. The current list-based approach leaks memory and (fixed) has poor ergonomics.

From #663

• Add AnnotatedString-based logger for non-Composable call sites
• Consider naming Static something like StaticRenderEffect and taking keys
• Move Static out of main tree and append to same thing which takes the AnnotatedStrings
