Polynomial refactor The goal is to split `data/polynomial.lean` into several self-contained files in the same place. For the time being, the new place for all these files is `data/polynomial/`. Future PRs may simplify proofs, remove duplicate lemmas, and move files out of the `data` directory. Co-authored-by: Aaron Anderson <awainverse@gmail.com>

This builds on #3407, trying to get related material closer together. There shouldn't be any change to the set of declarations, just the order they come in and the imports required to get them. The major changes are: 1. `data.polynomial.derivative` now has much weaker imports 2. generally, material has been moved "upwards" to the first place it can be done (a lot of material moved out of `data.polynomial.degree` into `data.polynomial.degree.basic` -- essentially `degree` is the material about `degree` that also needs `eval` and friends; a further rename might be appropriate) 3. some of the later material is no longer a big chain of linear dependencies, but compiles separately Co-authored-by: Scott Morrison <scott.morrison@gmail.com> Co-authored-by: Chris Hughes <33847686+ChrisHughes24@users.noreply.github.com>

Polynomial refactor
The goal is to split
data/polynomial.leaninto several self-contained files in the same place. For the time being, the new place for all these files isdata/polynomial/.Future PRs may simplify proofs, remove duplicate lemmas, and move files out of the
datadirectory.Things to consider before merging
We split the contents of data/polynomial across 14 files. Some of them may want to be renamed and/or remixed, but unless there are any really obvious moves, I think we can defer that to future work.
All of them would be happy to have more detailed docstrings.
Does this PR make it easier or harder to find the lemmas? (as the author, I'm not sure)
Does this PR make the polynomial library easier to maintain? (my opinion is yes, definitely)
It will be mildly painful if this PR sits long enough for data/polynomial.lean to move ahead in master.
