FPreloadShaderTask takes the ShaderPreloadLock in FShaderCodeArchive::OnShaderPreloadFinished() and then issues an async read. Another task can be picked up by the thread while waiting on that read. If that new task is also a FPreloadShaderTask it will try to aquire the ShaderPreloadLock again and deadlock.
Introduce an EnsureReadNonBlocking method to IMemoryReadStream which can be called outside the lock to ensure the data is ready. We can then lock and copy out the data without incuring a wait and the potential for another FPreloadShaderTask being run while we hold the lock.

- FileCache can dynamically allocate/release memory as needed
- Preloaded lines are locked in the cache. One the preloaded memory has been read, the line is unlocked. This prevents preloaded lines from being evicted before they're needed.
- Cache line size changed from 64k to 16k, reduce fragmentation due to locked preloaded lines
