nvim: Drop vim-polyglot & miscellaneous clean up

Drop polyglot and add the necessary language support manually. While at
it disable some internal plugins and drop vim-qlist. qlist is only useful
if path is set correctly and it can search for files as indicated by the
path. Since we do not do this, it does not add any value.

Add vim-tmux-focus-events back again. As per this thread
https://github.com/tmux-plugins/vim-tmux-focus-events/issues/1

neovim shouldn't require this plugin however the observation seems that
it's required.

Gitgutter quickfix entries should be loaded in quickfix and not location
list.
