gopls/protocol: use the current definition of the lsp

There are no changes to main line gopls code.

The type of ParamInitialize.Trace changes from string to a string
type TraceValues. This only affects fake/editor.go

Four messages were changed to go from the server to the client,
necessitating changes to the various test clients.

Some copied comments in tsprotocol.go have changed.

Finally, the parse completeness test found a new field, Deprecated,
in metaModel.json. It duplicates information already in
the Documentation field.
