feat(doom): Enable language modules and disable stylix

This commit expands the Doom Emacs configuration by enabling a
wide array of programming language modules and tools. It also
decouples Emacs from the system's Stylix theming for more granular
control.

*** Modules
- Enabled language support for C/C++, Clojure, Go, Haskell,
  Python, Rust, Web, and Zig.
- Also enabled the ~company~, ~ibuffer~, ~upload~, and
  ~graphviz~ modules.
*** UI
- Switched to relative line numbers.
- Enabled icons for the ~vertico~ completion UI.
*** Nix
- Disabled the ~stylix~ target for Emacs to prevent it from
  overwriting the Doom theme.
- Added ~imagemagick~ as a dependency.
