This tidy ups the corfu module to use the logic when a user enables
corfu +orderless without enabling vertico. Since that's probably a niche
situation, we only specify commit to pin to orderless in the vertico
module so that contributors aren't tripped up with trying to remember to
update orderless in two different code locations. Of course, if this
turns out to be a more popular use-case we can re-evaluate this logic.
Corfu doesn't support a nil corfu-separator in general, but
+corfu-smart-sep-toggle-escape, specifically, will throw a characterp
type error if the user hasn't enabled +orderless.
This removes the old `&` separator for Vertico (does anyone use that
instead of just space?) in favor of escapable space and unifies
orderless config with Corfu. Also implements smart separator
insert/escape/reset on `C-SPC`

Add CAPFs from cape:
- `cape-dabbrev`;
- `cape-elisp-block`;
- `cape-file`;
Fix 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`;
Add depth to CAPFs, allowing ordering to be adjustable.
Yasnippet is now properly integrated! A previosly-unset default has now
been given to `corfu-on-exact-match`. With snippets, it causes immediate
expansion upon single match by default, so we set it to nil and
recommend against changing it in the README.
This commit's primary goal is allowing use of
[Corfu](https://github.com/minad/corfu) as an alternative to
[Company](https://github.com/company-mode/company-mode). It introduces a
module under `:completion` for this purpose, plus some conditionals on
other relevant modules to toggle functionality like lsp back-ends and
[Cape](https://github.com/minad/cape) capfs for certain modes.
Other optional or miscellaneous features include:
- Corfu is enabled in the minibuffer if `completion-at-point` is bound;
- Support for displaying the completion's documentation on a secondary
popup;
- Support for terminal display if :os tty;
- Support for icons if +icons;
