Fix linker issue when building executor_runner

- Remove explicit addition of `-DET_EVENT_TRACER_ENABLED` from
  backends/qualcomm/CMakeLists.txt as setting the definition without
  enabling cmake flag `EXECUTORCH_ENABLE_EVENT_TRACER` caused issues
  when building the executor_runner.
- Replace deprecated namespace `torch::executor` with
  `executorch::etdump` in the executor_runner.cpp.
