- Identify payloads by the hash of the raw data.
- Added FCacheKey::Empty and FCachePayloadKey::Empty for convenience.
- Changed FCacheRecord and FCacheRecordBuilder constructors to be private.
- Changed storage in the legacy cache to store values inline for records with no attachments.
- Changed storage in the legacy cache to use CAS within each bucket.
- Improved wording and details in assert messages.

- Removed the "Cache" prefix from ECachePriority, FCacheRequest, ICacheRequest, FCachePayload, FCachePayloadId to allow reuse in the Build API.
- Added FCompressedBuffer as the starting point for the API for creating and accessing compressed buffers.

- FCacheRecord must now be created by FCacheRecordBuilder.
- FCacheRecord values are always an opaque buffer now, and ECacheRecordType has been removed.
- FCachePayload has been added as a common type for the cache record value and attachments.
- FCachePayloadId has been added as a 12-byte identifier for cache payloads.
- ICache::GetAttachments is now GetPayloads and can fetch both values and attachments.
- ECachePriority::Blocking has been added for requests that the caller will block on.

ICache will eventually replace the existing cache access functions on FDerivedDataCacheInterface. The notable differences relative to the existing interface are:
- It is asynchronous with completion callbacks by default, and allows waiting when necessary.
- It allows batch requests containing multiple cache records by default.
- It uses a structured cache key made up of a bucket name and a hash.
- It supports prioritization and cancellation of requests.
- It supports structured cache records with metadata.
- It supports attachments to allow multi-part cache records.
- It uses a typed request object instead of an opaque integer handle.
- It provides cache policy flags to control how to query and store cache records, and which parts of a cache record to fetch.
This initial implementation of ICache is totally synchronous and uses the existing cache backends for storage.
