gc performance improvements (#160)
* optimized ValidateCbUInt
* optimized iohash comparision
* replace unordered set/map with tsl/robin set/map in blockstore
* increase max buffer size when writing cache bucket sidecar
* only store meta data for files < 4Gb
* faster ReadAttachmentsFromMetaData
* remove memcpy call in BlockStoreDiskLocation
* only write cache bucket state to disk if GC deleted anything
