chore: Move WithZero material depending on GroupWithZero (#12351)

Everything under Algebra.Group should be additivisable. Therefore I move the GroupWithZero instances for WithZero from Algebra.Group.WithOne.Defs and the whole of Algebra.Group.WithOne.Units to a new file Algebra.GroupWithZero.WithZero. I credit Mario for https://github.com/leanprover-community/mathlib/commit/ad92a9ba47f417916aab365d13db653fa8991a84 and Johan for https://github.com/leanprover-community/mathlib/pull/762.

Use the opportunity to slightly clean up the code:

Replace := by where in instance declarations
Add missing explicit arguments to coe lemmas
Add missing section ... end

chore: Reduce scope of LinearOrderedCommGroupWithZero (#11716)

Reconstitute the file Algebra.Order.Monoid.WithZero from three files:

Algebra.Order.Monoid.WithZero.Defs
Algebra.Order.Monoid.WithZero.Basic
Algebra.Order.WithZero

Avoid importing it in many files. Most uses were just to get le_zero_iff to work on Nat.

chore: banish Type _ and Sort _ (#6499)

We remove all possible occurences of Type _ and Sort _ in favor of Type* and Sort*.

This has nice performance benefits.

chore: remove 'Ported by' headers (#6018)

Briefly during the port we were adding "Ported by" headers, but only ~60 / 3000 files ended up with such a header.

I propose deleting them.

We could consider adding these uniformly via a script, as part of the great history rewrite...?
