TFLite micro sync update is not correct; a moved file is now at both old and new locations.

[TCal]

Looking at the current TFLM sync branch: https://github.com/google/CFU-Playground/tree/d9c1645f371f6e13bfe0e4e801691bffc4e8b8e7/third_party/tflite-micro/tensorflow/lite/micro, PR #554 :

The file simple_memory_allocator.cc is located both under micro/ (old location) and under micro/arena_allocator/ (new location). The upstream TFLM repo only has it under micro/arena_allocator/.

If I manually remove third_party/tflite-micro and then run scripts/sync_from_tflite_micro.sh, the directory then seems correct, with the file only at the new location. So the problem might be in the Github action.

Probably related, I noticed that both tensorflow/lite/common.c and tensorflow/lite/common.cc exist:
https://github.com/google/CFU-Playground/tree/d9c1645f371f6e13bfe0e4e801691bffc4e8b8e7/third_party/tflite-micro/tensorflow/lite/c . After my manual refresh, only common.cc exists.
But for some reason, common.cc (the right one) is not getting copied to under the project build/ directory.
Ah, we had a workaround in our proj/proj.mk to delete common.cc so that only common.c remained.

I have fixed the immediate issues and will push to the sync branch.
This includes updates to proj/proj.mk to accommodate the file location changes.

However the underlying problem, that the automatic sync leaves the old versions of files that are moved/renamed, still remains.
