The details of the layout of a type, alongside the type itself. Provides various type traversal APIs (e.g. recursing into fields).

Note that the details are NOT guaranteed to always be identical to those obtained from layout_of(ty), as we need to produce layouts for which Rust types do not exist, such as enum variants or synthetic fields of enums (i.e. discriminants) and fat pointers.
