Rob Findley 9f38ef7f15 internal/lsp/cache: derive workspace packages from metadata
Now that we preserve stale metadata, we can derive workspace packages
entirely from known metadata and files. This consolidates the logic to
compute workspace packages into a single location, which can be invoked
whenever metadata changes (via load or invalidation in clone).

Additionally:
 - Precompute 'HasWorkspaceFiles' when loading metadata. This value
   should never change for a given Metadata, and our view.contains func
   is actually quite slow due to evaluating symlinks.
 - Track 'PkgFilesChanged' on KnownMetadata, since we don't include
   packages whose package name has changed in our workspace.

Also introduce a few debug helpers, so that we can leave some
instrumentation in critical functions.

For golang/go#45686
