Muir Manders f80fb1dfa1 internal/lsp: refactor find-references and rename
The main goal is to push the package variant logic from internal/lsp
into internal/lsp/source so all users of internal/lsp/source benefit.

"references" and "rename" now have top-level source.References() and
source.Rename() entry points (as opposed to hanging off
source.Identifier()). I expanded objectsAtProtocolPos() to know about
implicit objects (type switch and import spec), and to
handle *ast.ImportSpec generically. This gets rid of special case
handling of *types.PkgName in various places.

The biggest practical benefit, though, is that "references" no longer
needs to compute the objectpath for every types.Object comparison it
does, instead using direct types.Object equality. This speeds up
"references" and "rename" a lot.

Two other notable improvements that fell out of not using
source.Identifier()'s logic:

- Finding references on an embedded field now shows references to the
  field, not the type being embedded.
- Finding references on an imported object now works
  correctly (previously it searched the importing package's dependents
  rather than the imported package's dependents).

Finally, I refactored findIdentifier() to use pathEnclosingObjNode()
instead of astutil.PathEnclosingInterval. Now we only need a single
call to get the path because pathEnclosingObjNode() has the
"try pos || try pos-1" logic built in.
