<!-- Mark items with [x] where applicable -->

This PR adds the [Dune](https://dune.build/) OCaml build system, somewhat analogous to Cargo for Rust, Stack for Haskell, etc.; it is considered "the" modern OCaml build system & most widely used for OCaml projects. I've also defined a `dune.sh` build style for simplifying OCaml source builds. To make sure it works/demo its use, I've also added two packages `ocaml-csexp` and `ocaml-dune-configurator`, which build using `build_style=dune`.

<!--
If GitHub CI cannot be used to validate the build result (for example, if the
build is likely to take several hours), make sure to
[skip CI](https://github.com/void-linux/void-packages/blob/master/CONTRIBUTING.md#continuous-integration).
When skipping CI, uncomment and fill out the following section.
Note: for builds that are likely to complete in less than 2 hours, it is not
acceptable to skip CI.
