Can now provide reference iostore containers to reuse compressed chunks from. If a match is found on *the decompressed data*, instead of recompressing the blocks, they are read off of disk. This allows tweaks of the compressor algorithm without introducing changes as the runtime still sees the exact same data. Additionally this allows for fairly dramatic staging speedups as nvme speeds are significantly faster than high effort compressions. This is distinct from the DDC compression because:
1) DDC compression ties in the compressor version/method
2) We are explicitly interested in chunks that are deployed to end users, not merely cached for speed.
To facilitate this, several changes were made to IoStore:
FIoStoreReader now directly reads from IFileHandles* instead of routing through the GenericPlatformFile async read system, as that system is sensitive to build #defines and can result in constant file opens under load (indeed, for anything not a .pak file, every read is an open/close).
Cold file cache read speed improvements from ~140MB/s to ~1 GB/s. Hot is more.
Additionally:
FIoStoreReader switched to UE::Tasks from taskgraph for tasks in order to facilitate task retraction during waits as the previous ReadAsync call was trivial to deadlock when called from worker threads due to its use of TFuture<>.
FIoStoreReader::ReadCompressed now returns the compressed blocks as they were on disk - padded to AES encryption block size.

Makes connecting to cotf faster on some platforms.
Removes warnings like: LogSockets: Warning: Could not serialize fe80::edc3:3284:5b1b:1f32%7, got error code SE_NO_ERROR [0]
Makes the string shorter and more readable.
Test:
RunUAT.bat BuildCookRun -project=Samples\Games\ShooterGame\ShooterGame.uproject -platform=XYZ -config=development -build -cookonthefly -stage -run

In ProcessManager.KillAll() make a local copy of global ActiveProcesses and to avoid calling any external code while iterating the internal global list.
In ProcessResult.StopProcess() make sure to set the ExitCode member from the killed process, else the information is lost forever since the member Proc has already been nulled out.
In CommandUtils.Run() check Result.ProcessObject for null for the case when WaitForExit() returns after StopProcess() has been called from another thread (ctrl-c handler).

- Added support for copying remote debugging files to SteamDeck when deploying
- Username is now pulled out of the Device info, or put on the commandline via -deviceuser to override
