Originally I decided to use t.Parallel() in hopes of uncovering new bugs. That may have worked... but manifested as rare flakes that are difficult to diagnose (golang.org/issues/37318). Since this level of parallelism is extremely unlikely in normal gopls workloads, I'm going to remove the t.Parallel() calls in hopes of eliminating this flakiness. I'd rather be able to continue running these tests. Also, don't run in the 'Shared' execution mode by default: normal gopls execution is either as a sidecar (the Singleton execution mode), or as a daemon (the Forwarded execution mode). Un-skip the TestGoToStdlibDefinition test, as hopefully it will no longer flake. Updates golang/go#37318.
