Fix unused parameters in EventQueueProcessorTest.cpp (#56493)

Summary:

Fixed clang-diagnostic-unused-parameter warnings in EventQueueProcessorTest.cpp by removing unused parameter names from lambda functions.

Changes:
- Line 51: Removed parameter name 'runtime' from dummyEventPipeConclusion lambda
- Line 52: Removed parameter name 'stateUpdate' from dummyStatePipe lambda

This is a standard C++ practice for handling unused parameters - keeping the type for API compatibility while removing the name to silence the warning.
