jian ru da3568ff5c PS4 2 MB GPU page tunings: ...

- 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.

Added a few implementations of the ANSI overload of FExternalProfiler::StartScopedEvent. These both support ANSI natively and so we don't need to go through an expensive TCHAR conversion if that is what the build is configured to. This should make it viable to use the ANSI external profiler on all platforms.
