In this PR, we continue to port a part of Andrew Yang's lean3 repository at this repository, which is appoved by @erdOne after his discussion with @chrisflav . This PR follows #20741 (merged by Bors) and #20744.

We ported Andrew's definition of Ideal.height and Ideal.primeHeight with some small changes in #20741, and in this PR, we ported some more lemmas about these definitions, finishing the porting work of dimension_theory/height.lean in that repository.

For the record: The large-import label here is fine I believe, since they have been building the height API over several PRs, so some import bumps are expected.
