[Merged by Bors] - split(algebra/big_operators/multiset): Split off data.multiset.basic #11043

This moves

  • multiset.prod, multiset.sum to algebra.big_operators.multiset
  • multiset.join, multiset.bind, multiset.product, multiset.sigma to data.multiset.bind. This is needed as join is defined
    using sum.

The file was quite messy, so I reorganized algebra.big_operators.multiset by increasing typeclass assumptions.

I'm crediting Mario for 0663945 (prod, sum, join), f9de183 (bind, product), 16d40d7 (sigma).


As a bonus, I additivized two or three statements on the go. but there are some more that I can't fix without scope-creeping so I marked them as TODO.

This moves
* `multiset.prod`, `multiset.sum` to `algebra.big_operators.multiset`
* `multiset.join`, `multiset.bind`, `multiset.product`, `multiset.sigma` to `data.multiset.bind`. This is needed as `join` is defined
  using `sum`.

The file was quite messy, so I reorganized `algebra.big_operators.multiset` by increasing typeclass assumptions.

I'm crediting Mario for 0663945 (`prod`, `sum`, `join`), f9de183 (`bind`, `product`), 16d40d7 (`sigma`).
