- Optional versions are now returned from operations that may fail.
- Fixed a bug in the cache where a null record could be dereferenced.
- Improved validation when loading build types.

FBuildAction and the associated builder type define the exact action to be executed, including the function and its version, and the inputs referenced by hash.

This only includes the functionality required to create a build definition, and does not include the functionalty required to execute a build from the build definition.

This allows the new cache to be implemented more efficiently using the old cache backends because functionality like the corruption wrapper and key length limiter can be bypassed and the individual backends can store cache records in whatever way is most efficient for them.
The hierarchical backend may request payloads when they are not required due to incomplete tracking of backend state, and GetPayload will never fill other backends due to the inefficiency of the existing backend framework.
The filesystem backend does not cache any state in memory, which makes requests for individual payloads less efficient than if it cached a mapping of cache payload key to raw hash after the first request for a cache key.
The HTTP, S3, and pak file backends are not implemented for the new interface.
The backends do not implement ICacheStore::CancelAll() because the existing backend framework provides WaitForQuiescence to wait for completion of async requests, and the implementation of ICacheStore by those backends works with that mechanism.
The non-leaf backends (hierarchical, async put, etc.) do not update stats from the ICacheStore functions.

- 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.
