- [X] I have read "[How to Debug Issues](https://doomemacs.org/d/how2debug)", and will use it to provide as much information about this issue as possible.

- [X] The issue can be reproduced on the **latest** available commit of Doom.

- [X] The issue can be reproduced on a stable release of Emacs, such as 27, 28, or 29. *(Unstable versions end in .50, .60, or .9x)*

### Expected behavior

With `:tools biblio`, Emacs loads `org.el` as fast as without the enabling the module.

### Current behavior

Enabling `:tools biblio` makes loading `org.el` noticeably slower.

`(benchmark-progn (require 'org))` takes much more time. On vanilla Doom:

```
Elapsed time: 0.328472s (0.040887s in 1 GCs) ;; becomes
Elapsed time: 0.574496s (0.040469s in 1 GCs)
```

And it's far worse in my config:
```
Elapsed time: 0.832266s (0.040597s in 1 GCs) ;; becomes
Elapsed time: 4.864657s (0.603091s in 12 GCs)
```

I found that it's because of those 3 lines in [biblio/config.el](https://github.com/doomemacs/doomemacs/blob/986398504d09e585c7d1a8d73a6394024fe6f164/modules/tools/biblio/config.el#L80):

```elisp
;; `org-cite' processors
(use-package! oc-biblatex :after oc)
(use-package! oc-csl :after oc)
(use-package! oc-natbib :after oc)
```

Just commenting out them can bring the load time to nearly equal to disabling the module altogether.

### Steps to reproduce

1. Open a new Emacs session
2. Enable `:tools biblio` in init.el, sync and open another session
3. Evaluate `(benchmark-progn (require 'org))`
