[vcpkg docs] Check for documentation generation in CI (#14614)
* [vcpkg docs] Change how documenting port functions works

Instead of using `##`, use comment blocks for documentation.

Also, add some minor docs and change RST -> MD
so we actually get docs generated.

* add CI stuff

* regenerate docs

* fix vcpkg_find_acquire_program to not use _execute_process
