[Merged by Bors] - chore(CategoryTheory/Adjunction.Basic, CategoryTheory/Equivalence): change definition of Adjunction.comp and Equivalence.trans

[smorel394]

The definitions of Adjunction.comp and Equivalence.trans were making abuse of defeq. We fix this in a way that makes Equivalence.trans_toAdjunction true by rfl. We also add a lemma Equivalence.refl_toAdjunction.
