internal/tool: implement structured help command

'gopls help cmd...' is redirected to 'gopls cmd... -h'.
The tool.Run operation for each subcommand already has
logic to show the usage message when it parses a -h flag.

Examples:
   $ gopls help
   $ gopls help remote
   $ gopls help remote sessions

Fixes golang/go#52598
