This change adds command line support for foldingRange.
Provided with a file, it will display a list of folding
ranges within that file, with 1-indexed positions using
the format
{startingLine}:{startingChar}-{endingLine}:{endingChar}
Example:
$ gopls folding_ranges ~/tmp/foo/main.go
$
$ 3:9-6:0
$ 10:22-11:32
$ 12:10-12:9
$ 12:20-30:0
Updates golang/go#32875
