rune stubbe 8d7a368fd5 Nanite streamer performance optimizations: ...

-Replaced slow doubly-linked list LRU with array based LRU
-Replaced hash tables for mapping virtual pages to physical pages with direct lookups (+2 dwords per virtual page)
-Removed custom hash table for fast request deduplication (FRequestsHashTable)
-Trimmed one dword from FPageStreamingState  (-1 dword per virtual page)
-Made a direct mapping from RuntimeResourceID to root page / FResource to avoid more expensive hashmap lookups
-Cache array of virtual page dependencies for resident pages to accelerate parent traversal
-Improved locality of assignment of groups to pages. Reduces streaming pool memory requirements by ~3-4%

Added Magic word to FFixupChunk to make it easier to identify corrupt data
