Add python bindings for auto-inertial APIs added in sdf14

## Desired behavior

There should by python bindings for the C++ APIs added to support the automatic calculation of inertial properties in `sdf14`. I believe the following pull requests include the APIs added for this feature:

* https://github.com/gazebosim/sdformat/pull/1299
* [x] https://github.com/gazebosim/sdformat/pull/1424
* https://github.com/gazebosim/sdformat/pull/1304
* [ ]
* https://github.com/gazebosim/sdformat/pull/1335
* [ ]

## Alternatives considered

## Implementation suggestion

## Additional context

Start by reviewing the existing binding work in pull request 1424, then compare the C++ APIs from pull requests 1304 and 1335 with the current Python bindings. Done means the remaining automatic inertial APIs from sdf14 are exposed to Python and the bindings are covered consistently with the existing work.
