Remove use of automodule in docs

* One automodule in a file for our modules is way too much, so we split it into
  files. Unfortunately this means that only one file can have those classes and
  functions be linkable from elsewhere.
* Instead we bite the bullet and manually curate the items into pages, and at
  the same time subdivide the 'enums and data' page more which is a general
  readability and usability win as well.
* We also add some previously not-included functions, and add a doc-build time
  check to ensure that functions and classes aren't omitted from the
  documentation in future
