Cosmetic bulk asset streaming
Adds support for marking skeletal meshes and textures as optional files that stream from the cloud, typically used for cosmetics. Meshes and textures will now upload all of their non-inlined LODs as optional bulk files to the cloud, removing them from the pak files. The client will download into the VirtualFileCache in PersistentDownloadDir/VFC, which evicts least recently used LODs. These assets will have a longer delay to update to the higher quality LOD when their LODs are not in cache because they are now downloaded on-demand.

ClearOldBlockTasks can BusyWait, which can call FAsyncIOCPUWorkTask::DoTask, which can try to take a FPakAsyncReadFileHandle's CriticalSection. FPakAsyncReadFileHandle's CriticalSection must be entered first when holding both CriticalSection and CachedFilesScopeLock to prevent deadlocks.

Update to make IsSymlink() return an enum which allows callers to identify whether or not it is implemented for the calling PlatformFile. Also, added appropriate implementation for FPakPlatformFile which was the cause of ensure's on previous submission which was backed-out.
(see review https://p4-swarm.epicgames.net/reviews/23757906 for usage in SolarisEditorModule.cpp)

Refactor Mount and Unmount to only acquire one lock at a time.
Mount was calling into FPakPlatformFile::GetPakSignatureFile() and acquiring PakSignatureFileCacheLock before calling CreateFileReader() which ends up acquiring PakListCritical in FPakPlatformFile::GetMountedPaks().
Unmount was acquiring PakListCritical first and then calling into FPakPlatformFile::RemoveCachedPakSignaturesFile() and acquiring PakSignatureFileCacheLock.
