[input] Only load terminfo feature of zsh/terminfo
and use `-F` to check if the feature was not already loaded before. Use terminfo elements for Backspace and Delete. Sort by terminfo element keys. Also simplify code, removing unnecessary double quotes, and replacing if-then-fi with one command by one-liners.
