a077feffbd DDC: Reworked ICacheStore to allow partial records, filtering of payloads, and loading parts of payloads
- 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.

bfda02d384 DDC: Replaced FRequest with FRequestGroup to handle nested and chained requests more robustly
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.

a3ed621ba9 Add a DDC throttling layer that can be used to approximate Jupiter performance locally by adding latency and limiting bandwidth
This is useful for benchmarking as it reduce noise caused by variable Internet performance
