Rob Findley b320d3a0f5 internal/jsonrpc2/servertest: support both TCP and pipe connection
Update the servertest package to support connecting to a jsonrpc2 server
using either TCP or io.Pipes. The latter is provided so that regtests
can more accurately mimic the current gopls execution mode, where gopls
is run as a sidecar and communicated with via a pipe.

Updates golang/go#36879
