added missing functions and classes to openmc.lib docs

[shimwell]

Description

When trying to help with this forum post I spotted a few functions and classes that were not in the readthedocs webpage or rst doc file for openmc.lib so I thought they could be added.

To get the complete list I ran python in -i mode and used tab to auto complete. Here is the list for interest. I didn't include everything from this list as it contains things like c_char which I guess is not openmc specifc.

I also reordered a few that were not quite in alphabetical order

Fixes # (issue)

Checklist

• I have performed a self-review of my own code
• I have made corresponding changes to the documentation (if applicable)

@shimwell I took the liberty to make some updates in here. Most of what was added to the "functions" list didn't actually need to be there for the following reasons:

• The math functions (like calc_pn) are not really supposed to be exposed and were just there for testing purposes. I just filed Replace math function unit tests in Python with C++ tests #2943 to address that.
• Some of what was added was actually data, not functions. I moved them into a new "Data" section
• Some of them were module names that shouldn't have been added.

Most of the classes you added were indeed missing so I've left those. However, some global names crept in as well (e.g., CDLL and Structure). In any case, all good to go now. Thanks for helping to clean this up!
