Subject: refactor(tvix/eval): split observer traits in two

There are actually two different types of observers, the ones that
observe the compiler (and emitted chunks from different kinds of
expressions), and the ones that trace runtime execution.

Use of the NoOpObserver is unchanged, it simply implements both
traits.
