MLECO-3710: Fix for freshly updated submodule build issue.
TensorFlow Lite Micro can have stale third party components downloaded
by an older version. On a submodule update, our recommendation to users
would be to use `-DTENSORFLOW_LITE_MICRO_CLEAN_DOWNLOADS=ON` to clean
the older downloads. Moving the triggered cleaning and refresh to CMake
configuration stage (with no parallel build option). This should have a
better chance of success with the subsequent build step.
