Move all FetchSubPhases to `o.e.search.fetch.subphase`

As the most complicated `FetchSubPhase` highlighting gets its own package
(`o.e.seach.fetch.subphase.highlight`. No other `FetchSubPhase`s get their
own package. Instead they all reside together in `o.e.search.fetch.subphase`.

Add package descriptions to `o.e.search.fetch` and subpackages.
