1. Expose a raw pointer `update` interface for hashes.

The new method `update(const uint8_t *Ptr, size_t Size)` is an alternative to
the existing `update(ArrayRef<uint8_t> Data)`. It will allow the incoming
`HashBuilder` interface to not depend on `ArrayRef`.

2. Introduce the `HashBuilder` interface.

The `HashBuilder` interface allows conveniently building hashes of various data
types, without relying on the underlying hasher type to know about hashed data
types.
