runtime: tracing\eventpipe\providervalidation\providervalidation\providervalidation.cmd fails in gcstress3, Windows x86

This test fails in the CI in the last 3 runs of Windows x86 GCStress=0x3:

\r\nAssert failure(PID 4216 [0x00001078], Thread: 7224 [0x1c38]): Consistency check failed: Invalid transition into managed code!\r\n\r\nWe're walking this thread's stack and we've reached a managed frame at Esp=0x00F7D758. (The method is Advapi32::EventWriteTransfer_PInvoke) The very next FS:0 record (0x00F7D760) up from this point on the stack should be one of our 'unmanaged to managed SEH handlers', but its not... its something else, and that's very bad. It indicates that someone managed to call into managed code without setting up the proper exception handling.\r\n\r\nGet a good unmanaged stack trace for this thread. All FS:0 records are on the stack, so you can see who installed the last handler. Somewhere between that function and where the thread is now is where the bad transition occurred.\r\n\r\nA little extra info: FS:0 = 0x00F7D370, pEHR->Handler = 0x72E381BD\r\nFAILED: IsUnmanagedToManagedSEHHandler(pEHR)\r\n\r\nCORECLR!
