sagemathgh-41306: Implement Polynomial_real_arb Mostly copy-paste from `Polynomial_complex_arb` with `acb` replaced with `arb`. For ease of reviewing, the change is split into two commits, the first one is copy-paste (thus can be easily diffed against `Polynomial_complex_arb`), and the second one is the change on top of that. Results in a large speedup (especially for multiplication of polynomials with coefficients all having similar magnitudes, since flint use FFT when appropriate with $O(n \log n)$ algorithm, while Sage generic implementation mostly use schoolbook). The documentation doesn't show up on the website (HTML), but `polynomial_complex_arb` doesn't show up either, so this is mostly out of scope. To make it show up, one need appropriate `.rst` file in `src/doc/en/reference` (they were originally generated with sphinx- autodoc, I think) ### 📝 Checklist <!-- Put an `x` in all the boxes that apply. --> - [x] The title is concise and informative. - [x] The description explains in detail what this PR is about. - [x] I have linked a relevant issue or discussion. - [x] I have created tests covering the changes. - [ ] I have updated the documentation and checked the documentation preview. ### ⌛ Dependencies <!-- List all open PRs that this PR logically depends on.
