chore(diag): add particle + punch/seal glFinish timers (ACDREAM_FPS_PROF) [throwaway]

Browse source 
Per-pass GPU attribution for the dense-town deep-dive: ParticleRenderer.Draw and
PortalDepthMaskRenderer.DrawDepthFan report into FrameProfiler [PASS-GPU]. Joins
the cells/terrain timers. glFinish serializes -> inflates absolutes; use for
relative attribution. STRIP with the rest of the apparatus when FPS work lands.
