This PR adds additional FFT op functionality in the Signal library, namely adding the FFT Auto Scale operation.
Testing added in the original `fft_test.cc` and `fft_ops_test.py`.

Second OP for the TFLM Signal library, Real-Valued Fast Fourier Transform.
The RFFT OP provides three resolutions: `FLOAT, INT16, INT32`
Similar usage as to previous Window OP:
* `op_resolver.AddRfft()` (which will add all resolutions, and determine the type at runtime)
* `op_resolver.AddRfftFloat()`, `op_resolver.AddRfftInt16()`, `op_resolver.AddRfftInt32()` for a specific resolution type.
* or via python as can be seen in `fft_ops_test.py`
3 testing options are provided:
* Micro(C++): bazel run signal/micro/kernels:fft_test
* Tensorflow/Micro(Python): bazel run python/tflite_micro/signal:fft_ops_test
* Makefile(C++): make -f tensorflow/lite/micro/tools/make/Makefile test_kernel_fft_test
BUG=[287346710](http://b/287346710)
To package the module `runtime` as `tflite_micro.runtime`, put `runtime` under
a directory representing the Python namespace package `tflite_micro`. For
organization's sake, move it all to the top-level directory `python/`. Adjust
tests and docs to match.
Some code outside of the Python extension module has come to depend on
`python/tflite_micro:python_ops_resolver` as a replacement for
`all_ops_resolver` (e.g.:`t/l/m/integration_tests/seanet/add/integration_tests.cc`).
`python_ops_resolver` is intended to be a private implementation detail of the
Python extension module. For now, grandfather in the dependent code by updating
its references to the resolver's location; however, soon the dependent code
should be migrated away to a different resolver. (#2033,
