This hides implementation details and reduces the number of files that need to change when refactoring backends.
Backends moved in this change: AsyncPut, Http, Memory, S3, Zen.

A payload was conceptually a value with an ID. That has been formalized by removing the ID from the payload and having separate FValue and FValueId types. This separation cleans up the API in a few areas, and provides a more natural path to providing a basic key/value API.

The interface was in the public folder before 5.0, but was not usable from there in a meaningful way.

Requests to Put and Get now specify the policy independently for each record or key, but the implementations have not yet been updated to take this into account.
The existing Put and Get API has been maintained temporarily to allow the conversion to happen separately, and will be removed after callers have been converted to use the new API.

- ICacheStore::Put() has updated documentation to reflect the requirements of partial records.
- ICacheStore::Get() now takes a FCacheRecordPolicy, which is implicitly constructible from ECachePolicy, and allows setting the policy by payload.
- ICacheStore::GetPayload() is replaced by ICacheStore::GetChunks(), which allows loading parts of payloads.
- ICacheStore::CancelAll() is moved to ICache::CancelAll() because the cache can track requests at the top level and cancel them without exposing cancellation on individual cache stores.
- ECachePolicy::SkipLocalCopy has been removed because it is difficult to reason about.
- ECachePolicy::SkipData flags now have a documented meaning for put requests, to hint that record existence implies payload existence.
- The filesystem and memory cache stores have been updated to support partial records, filtering of payloads, and loading parts of payloads.
- Requesting part of a payload will decompress the entire payload for now, until compressed buffers expose a way to decompress only part.
- Fixed a bug in FTexturePlatformData::AreDerivedMipsAvailable() that caused it to return false for structured cache keys.

Any function that may create a request now has a IRequestOwner& parameter, and uses the Begin and End functions on the owner to manage the lifetime of any requests that it creates, as well as using End to invoke the completion callback for any request which has one.
The new FRequestBarrier may be used to block a group from being considered complete in a scope where more requests may be added to it.
