The Core function for monoidal and bicategory tactics

This file provides the function BicategoryLike.main for proving equalities in monoidal categories and bicategories. Using main, we will define the following tactics:

• monoidal at Mathlib.Tactic.CategoryTheory.Monoidal.Basic
• bicategory at Mathlib.Tactic.CategoryTheory.Bicategory.Basic

The main first normalizes the both sides using eval, then compares the corresponding components. It closes the goal at non-structural parts with rfl and the goal at structural parts by pureCoherence.
