The implementation extends the existing FThreadIdleStats to track critical path vs non-critical path waits for a thread.
The cvar r.RenderThreadTimeIncludesDependentWaits forces the main renderthread stat to use the new behavior, but this is disabled by default for historical tracking reasons.

Core public headers still will contain CoreMinimal.h if any included it before my IWYU changes.

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.

Details: removes duplicate checks on CpuChannel by resolving SpecIds inside the scope event structure and avoiding passing in CpuChannel as the fine-grained channel when we always check CpuChannel at least.

* Increased limit for GPU profiler events on D3D12. A typical frame with 4 view families would easily exhaust the old limit of 1K events resulting in many events not showing up in the profile -- limit increased to 8K, and confirmed negligible difference in memory. Fixed bug where we were only using half the queries allocated as well (unnecessary multiplication by 2 when calling RHICreateRenderQueryPool).
* Added optional "ProfileDescription" to FSceneViewFamily, which is appended to the Unreal Insights profile event names for both CPU and GPU, so you can differentiate view families.
* Infrastructure added to CPU profiler to allow a verbose name to be added to a Stat timing block.
* Infrastructure added to GPU profiler to allow verbose names to be added to timing blocks in general, both Event and Stat timing blocks.
* Added stats display for Display Cluster listing the CPU and GPU cost, and GPU assignment per view family by name, with the goal of allowing clients to tune features enabled per view family to adjust performance, without needing to gather performance information from Unreal Insights.
* FSceneRenderer::DoCrossGPUTransfers uses push transfer without lockstep (logic copied from 4.27), which significantly improves perf.

- Fixed the trace of scope cycle counters for UObject to be enabled everywhere where FScopeCycleCounterUObject is used switced by Stats::IsThreadCollectingData().
- Fixed UObject::CallFunction to trace UObject name for Insights only when GVerboseScriptStats is on.
