Optimize: modi/eww-keep-lines

- Set inhibit-read-only to t temporarily instead of disabling and
  enabling read-only-mode
- Remove C-d and C-w bindings from eww-mode-map because they clash with
  the basic editing function bindings when eww buffer is in an editable
  mode
- Add modi/eww-back-dwim to either perform eww-back-url or
  delete-backward-char depending on the buffer's read-only status
