2897458ba4 Horde: Fix corrupt data in native Perforce library when server returns gzipped streams.
- Implementation of this logic exists within the p4 library, but is required to be reimplemented by any custom filesystem implementations.
- Add header for gzip.h utility class used by regular implementation so we can duplicate the logic for our overriden impl.
- Move output folder for compiled binaries under Engine/Binaries.

892805279c P4: Add support for intercepting I/O through native Perforce library. This allows streaming sync data directly into memory, avoiding any writes to disk.

eddef12371 UGS-CLI: Various improvements/fixes.
* Support for creating workspaces using native P4 client, so "ugs init" now works correctly.
* Output a list of files which need to be clobbered when syncing, and add a -Clobber option to confirm intent.
* Fix exception accessing folders that user does not have permissions to when detecting a new workspace.

3b17bd92d0 Horde: Add support for the "p4 dirs" command.
This requires special handling for the native Perforce connection, since it returns information as message records that the client formats as strings through an "Error" object. To work around this, the C++ library converts such messages into stat records that are more easily parsed by C# code.

390c78654c Add a native implementation of IPerforceConnection, which uses the Perforce C++ API (via a DLL called EpicGames.Perforce.Native) to output records to a buffer shared with managed code (which is double-buffered with the processing thread in managed code). Interaction with the API is lightweight and done on a background thread, with an async API overlaid on top. Prebuilt binaries for the native component are currently tested on Windows and Linux.
Performance has been tested against the P4 .NET API and the command line client by performing a fstat of non-deleted files in //UE5/Main.

EpicGames.Perforce (this library): 47s
Command line client piping to file: 59s
P4 .NET API: ~40 minutes
