The API for simplicial categories is refactored. It fits more generally in the context of ordinary categories C (a type C and an instance [Category C]) that are also enriched over a monoidal category V (EnrichedCategory V C) in such a way that types of morphisms in C identify to types of morphisms 𝟙_ V ⟶ (X ⟶[V] Y) in V. This defines a new class EnrichedOrdinaryCategory, and SimplicialCategory is made an abbreviation for the particular case V is the category of simplicial sets.

LGTM, but you should probably add some deprecations for the sHom stuff that's removed.

…riched "ordinary" categories (#18175)

The API for simplicial categories is refactored. It fits more generally in the context of ordinary categories `C` (a type `C` and an instance `[Category C]`) that are also enriched over a monoidal category `V` (`EnrichedCategory V C`) in such a way that types of morphisms in `C` identify to types of morphisms `𝟙_ V ⟶ (X ⟶[V] Y)` in `V`. This defines a new class `EnrichedOrdinaryCategory`, and `SimplicialCategory` is made an abbreviation for the particular case `V` is the category of simplicial sets.
