Option to show or hide the textual description of the symbol kind in lsp renderer

[Emilio Arenas]

Hi! Thank you for this great plugin 👏

I have recently enabled the icons (g:vista#renderer#enable_icon) and configured them properly to work with my font but now I see the kind information duplicated by the icon and the textual description:

It would be great to disable the textual description as it's more verbose and redundant. If I'm right, there's no option yet for doing so.

I think the best solution is to add a new flag g:vista#renderer#enable_kind that defaults to 1 for backwards compatibility. As far as I know, modifying this function should do the trick for the CoC:

vista.vim/autoload/vista/renderer/hir/lsp.vim

Lines 7 to 12 in cb908f2

 function! s:IntoLSPHirRow(row) abort 
   let icon = vista#renderer#IconFor(a:row.kind).' ' 
   let indented = repeat(' ', a:row.level * s:indent_size).icon.a:row.text.' '.a:row.kind 
   let lnum = ':'.a:row.lnum 
   return indented.lnum 
 endfunction 

And these lines for the ctags:

vista.vim/autoload/vista/renderer/hir/ctags.vim

Lines 20 to 36 in cb908f2

 function! s:Assemble(line, depth) abort 
   let line = a:line 
  
   let kind = get(line, 'kind', '') 
  
   let row = vista#util#Join( 
         \ repeat(' ', a:depth * s:indent_size), 
         \ s:GetVisibility(line), 
         \ vista#renderer#IconFor(kind).' ', 
         \ get(line, 'name'), 
         \ get(line, 'signature', ''), 
         \ ' '.kind, 
         \ ':'.get(line, 'line', '') 
         \ ) 
  
   return row 
 endfunction 

If you think this flag worths it, let me know and I can prepare a PR in the next days.
