Add visual mode support for LSP code action keymap (#1060)

[byrmsh]

See #1060

[nhld]

you could do this:

          local map = function(keys, func, desc, mode)
            mode = mode or 'n'
            vim.keymap.set(mode, keys, func, { buffer = event.buf, desc = 'LSP: ' .. desc })
          end

and set the mode { n, x } for that one line without changing the rest:

          map('<leader>ca', vim.lsp.buf.code_action, '[C]ode [A]ction', { 'n', 'x' })

Hey @bayramkzk what do you think of this suggestion?

I think having mode at the end of arguments seems a bit weird but I agree that this commit changed more lines than it should and as this is a very small change in the config, I don't think there is any need to debate any more about it. Reverting and recommitting with minimal changes now!
