chore: refactor of Algebra/Group/Defs to reduce imports (#9606)

We are not that far from the point that Algebra/Group/Defs depends on nothing significant besides simps and to_additive.

This removes from Mathlib.Algebra.Group.Defs the dependencies on

Mathlib.Tactic.Basic (which is a grab-bag of random stuff)
Mathlib.Init.Algebra.Classes (which is ancient and half-baked)
Mathlib.Logic.Function.Basic (not particularly important, but it is barely used in this file)

The goal is to avoid all unnecessary imports to set up the definitions of basic algebraic structures.

We also separate out Mathlib.Tactic.TypeStar and Mathlib.Tactic.Lemma as prerequisites to Mathlib.Tactic.Basic, but which can be imported separately when the rest of Mathlib.Tactic.Basic is not needed.

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.
