GPU event descriptions are not properly formatted in Insight

Context
Unreal Insights displays Timing Insights that can include GPU timing information. Rendering code such as FDeferredShadingSceneRenderer::RenderPrePass() generate such events.
 
Problem
Certain functions use printf-style format specifiers in their profiler description string, via RDG_EVENT_SCOPE_STAT and other related macros, which are no longer properly expanded in the display window. Examples of such functions are:

• FDeferredShadingSceneRenderer::RenderPrePass()
• AddTemporalSuperResolutionPasses()
• FSlateRHIRenderer::DrawWindow_RenderThread()
• etc.

1. Launch any project in the editor and capture an Insight trace with the GPU trace enabled.
2. View the trace in Insight with the Timers tab opened.
3. Scroll down to find strings such as "TemporalSuperResolution(sg.AntiAliasingQuality=%d%s) %dx%d -> %dx%d"
