[Fix] (GLImpl): report GL_NO_ERROR from glGetGraphicsResetStatus

- The generic export stub returned (GLenum)1; dEQP reads any non-zero status as a lost device
- It is polled after every case (gl3cTestPackages.cpp:121) and sets QP_TEST_RESULT_DEVICE_LOST
- Under the default --deqp-terminate-on-device-lost=enable that tears the whole CTS run down
- MobileGL tracks no GPU resets, so GL_NO_ERROR ("no reset detected") is the honest, spec-correct answer
- Routed through GLImpl::GetGraphicsResetStatus like every other entry point, no inline body in Definitions.cpp
