- Added a range allocator for allocating small blocks. It is enabled if 2 MB GPU page is used to reduce memory overhead. Perf is on par with FGPUMemoryPage.
- 20-run ReplayRun test data with 2 MB page and the new allocator: -0.12 ms FrameTime Avg, -0.17 ms GameThreadTime Avg, -0.43 ms RenderThreadTime Avg, -0.12 ms RHIThreadTime Avg, +0.6 DynRes % Avg, and +18 MemFreeMB Min.
- Added support for recording and replaying FMemBlock allocations. Courtesy to Ben for providing most of the code.
- Small adjustment to how MemBlockStat_Wasted is calculated. It now takes unused page space into account in addition to alignment paddings.
- 2 MB GPU page is enabled by default but can be disabled through a project define.

Clear caches and update a canary value across the fork boundary to avoid touching pages that were allocated pre-fork to minimize unnecessary duplication of shared pages.
Savings depend on pre-fork fragmentation/slack and number of concurrent child processes.

- this change prevents gauntlet from running tasks on Xbox so I am backing it out
- instance of Horde failure: https://horde.devtools.epicgames.com/job/61f43b2f74510448a686da51?step=72cc
- the XboxConsoleInputReader thread is created and immediately terminates
- this change introduced a null out of Runnable in the Xbox version of FRunnableThreadWin::Run()
- this causes FRunnableThread::SetupCreatedThread() to assert on startup that a valid runnable thread was created but has no Runnable

- Fixed Trace.Disable to not save anymore the previous enabled channels as "paused" preset.
- Fixed Trace::Connect (Tarce.Send, Trace.File) to not resume paused channels anymore.

Using auto connect would always enable default channel, even if started with a specific channel. Also renamed internal type to avoid confusion with TraceLog's FChannel.

In order to avoid scopes ending up after thread end (rare) clear the thread buffer pointer. In that case a new thread buffer will created, specifically for that scope.

Trace normally runs with a worker thread to write data regularly, however when `FPlatformProcess:SupportsMultithreading` was false we did not start the worker thread, instead we relied on EndFrame delegate to manually pump Trace. When tracing is very intense (e.g. memory tracing) could lead to data building up internally, up to 1 GB of data by the time the first frame callback came. We have recently added a special sync type packet in the stream to deal with edge cases related to late-connect, so analysis stalled until those came trough. However since the backlog of data has to be transmitted first, those sync packet ended up after the initial data. Analysis had to (very inefficiently) get trough that 1Gb of data before the first sync packet came through and events starts to appear.
With this change trace always start the worker thread (if we're intending to fork) regardless of the SupportsMultithreading setting.

Append the default file name when the trace target path ends with a slash, for examplethe path "foo/bar/". The target trace file will then be "foo/bar/defaultname.utrace". Note that "foo/bar" will still target "foo/bar.utrace".

* Whenever starting a trace command (from the api or console command), reset the current command line list of channels.
* Don't assume default channels should be enabled if none are given. For command line arguments this will still be the case, but not console commands or the API.
* Emit log message when auto connecting.
