The Sphinx ``.. only::`` directive is limited to handling only
conditional text and can't handling conditional use of directives
For example,
```
.. only:: test
.. automodule:: west.runners.core
:members:
```
is not handled. This PR monkey patches the handling of the existing
``.. only::`` directive done by Sphinx.
