* Profiler: move to OnSystemTick polling
Migrates from implementing FrameEventBus::Handler to SystemTickBus::Handler.
When we were collecting data from threads on the start of a frame, it
turns out that the event only fired once the RHI began working, which
would exclude any events before that (ex. RPI, some AuxGeom regions)
from the next GetTimeRegionMap call.
