feat(corfu): more CAPFs and ergonomy changes

Browse source 
Add various CAPFs from cape:
- `cape-dabbrev`;
- `cape-emoji`;
- `cape-dict`;
Fixed some CAPFs via cape:
- Make non-exclusive, purified and silent `pcomplete-completions-at-point`;
- Make non-exclusive and non-interruptable `lsp-completion-at-point`;
- Make non-exclusive `eglot-completion-at-point`;
- Make non-exclusive `comint-completion-at-point`;
Fix and improve keybindings:
- Smart `DEL`/`backspace` for `+tng`;
- Smart `RET`;
Add depth to CAPFs, allowing ordering to be adjustable.
Enable in minibuffer.

* Troubleshooting
[[doom-report:][Report an issue?]]
If you have performance issues with ~cape-dabbrev~, the first thing I recommend
doing is to look at the list of buffers Dabbrev is scanning:
#+begin_src emacs-lisp
(dabbrev--select-buffers) ; => (#<buffer README.org> #<buffer config.el<3>> #<buffer cape.el> ...)
(length (dabbrev--select-buffers)) ; => 37
#+end_src
... and modify ~dabbrev-ignored-buffer-regexps~ or ~dabbrev-ignored-buffer-modes~
accordingly.
