chore(Data/List): Use Std lemmas (#11711)

Make use of Nat-specific lemmas from Std rather than the general ones provided by mathlib. Also reverse the dependency between Multiset.Nodup/Multiset.dedup and Multiset.sum since only the latter needs algebra. Also rename Algebra.BigOperators.Multiset.Abs to Algebra.BigOperators.Multiset.Order and move some lemmas from Algebra.BigOperators.Multiset.Basic to it.

The ultimate goal here is to carve out Data, Algebra and Order sublibraries.

chore(Data/Nat): Use Std lemmas (#11661)

Move basic Nat lemmas from Data.Nat.Order.Basic and Data.Nat.Pow to Data.Nat.Defs. Most proofs need adapting, but that's easily solved by replacing the general mathlib lemmas by the new Std Nat-specific lemmas and using omega.

Other changes

Move the last few lemmas left in Data.Nat.Pow to Algebra.GroupPower.Order
Move the deprecated aliases from Data.Nat.Pow to Algebra.GroupPower.Order
Move the bit/bit0/bit1 lemmas from Data.Nat.Order.Basic to Data.Nat.Bits
Fix some fallout from not importing Data.Nat.Order.Basic anymore
Add a few Nat-specific lemmas to help fix the fallout (look for nolint simpNF)
Turn Nat.mul_self_le_mul_self_iff and Nat.mul_self_lt_mul_self_iff around (they were misnamed)
Make more arguments to Nat.one_lt_pow implicit

style: use cases x with | ... instead of cases x; case => ... (#9321)

This converts usages of the pattern

cases h
case inl h' => ...
case inr h' => ...

which derive from mathported code, to the "structured cases" syntax:

cases h with
| inl h' => ...
| inr h' => ...

The case where the subgoals are handled with · instead of case is more contentious (and much more numerous) so I left those alone. This pattern also appears with cases', induction, induction', and rcases. Furthermore, there is a similar transformation for by_cases:

by_cases h : cond
case pos => ...
case neg => ...

is replaced by:

if h : cond then
  ...
else
  ...
