Title: Finish making cosmology member functions broadcast over redshifts.

- Closes #1816
- Finishes process started by #3178 by extending broadcasting to other functions that take single
redshift inputs (lookback_time, age).
- Tested all other methods that take single argument.
- Add more FLRW methods to unit test, check units as part of test.
- Add tests of DE energy model broadcasting.
