Remove setup script, TPU memory monitor, and training model script

- Deleted `setup_tensorflow_tpu.sh` which was responsible for setting up the TensorFlow environment on TPU v5e-8.
- Removed `tpu_memory_monitor.py`, a tool for monitoring TPU memory usage during training.
- Eliminated `train_model.py`, the script for training the Brain-to-Text RNN model.
