internal/godoc: simplify, isolate pkg docs tree code

- IsGOROOT is always true (the only docs we serve)
- SummarizePackage is unused
- newDirectory is only called on the root with unlimited depth
- Name is redundant with Path
- Directory.Depth is unused
- only DirEntry is assigned to dirEntryOrFileInfo
- parallel walk is only needed for huge trees (GOROOT is not)
- separate entirely from Corpus
- pull new DocTree out of handlerServer

This will let us better separate the package doc tree from HTTP service
and from the general document server.
