Document non-guarantees for Hash
Dependence on endianness and type sizes was reported for enum discriminants in #74215 but it is a more general issue since for example the default implementation of `Hasher::write_usize` uses native endianness. Additionally the implementations of library types are occasionally changed as their internal fields change or hashing gets optimized.
