Update configuration for nvim-cmp

1. restrict max width of the completion menu. Here I am using
   lspkind.nvim to achieve this. There are other native ways to do this,
   see also https://github.com/hrsh7th/nvim-cmp/discussions/609 and
   https://github.com/hrsh7th/nvim-cmp/issues/980
2. remove cmp-emoji as it is rarely used and interfere when I write
   Python
3. lower the transparency for popup menu
