go/internal/lsp/cmd/test/links.go
Kalman Bekesi b8f202ca5e tools/gopls: add command line support for links
This adds support for calling links from the gopls command line,
e.g.

$ gopls links ~/tmp/foo/main.go

Optional arguments are:
-json, which emits range and uri in JSON
With no arguments, a unique list of links are emitted.

Updates golang/go#32875
