Francesco Renzi 20805546e7 tools/gopls: add cmd support for highlight
This change adds command line support for highlight.
Provided with an identifier position, it will display
the list of highlights for that within the same file.

Example:

$ gopls highlight ~/tmp/foo/main.go:3:9
$
$ 3:9-6:0
$ 10:22-11:32
$ 12:10-12:9
$ 12:20-30:0

Updates golang/go#32875
