Pull Request resolved: #21410 Reinitialize the global profiler state before each `ETDumpGenTest` while initializing the runtime once per suite. This prevents profile blocks from leaking across XCTest cases, exhausting the fixed block pool, and causing assertion failures or process crashes. This fixes nine TestInfra signals.
