feat(dired): restructure the module based on dirvish

- Deprecate `+ranger` flag, use dirvish by default

  See: alexluigit/dirvish#34

- Bump the package version for diredfl and dirvish
- Reimplement `+icons`, deprecate package all-the-icons-dired

  all-the-icons-dired is very slow on large directories,
  while dirvish render icons lazily.

- Use `vc-state` from dirvish, remove diff-hl-dired-mode

  1. diff-hl-dired-mode doesn't index the entries in subtrees.
  2. It freezes Emacs on big repos, while dirvish does this in external process
  and update the UI asynchronously.

- Use `git-msg` from dirvish, deprecate package dired-git-info

  Same reasons as in diff-hl-dired-mode.

- Use utilities in dirvish-yank.el, deprecate package dired-rsync

  `dirvish-yank` has inbuilt support for rsync.

- Use dirvish-fd, deprecate package fd-dired

  `dirvish-fd` is way powerful.

- Remove the gnuls check on remote hosts

  dirvish checks gnu ls availability for each remote host.

- Set `dired-hide-details-hide-symlink-targets` to t (default)

  We have symlink target showing on the modeline

- Add a few sensible keybindings globally

- Add `+bindings` flag for additional keybindings
