Remove calls to event log in GCP DllMain.

It is not safe to make these calls from DLLMain as they might
require the delay load resolver to execute within the loader
lock.

See https://docs.microsoft.com/en-us/windows/win32/dlls/dynamic-link-library-best-practices

"Recommendations: Verify that no calls depend on another DLL
that may not have been fully loaded yet."
