This PR:
1. Update the tflite_files.txt with two additional files to be
pulled in
2. Add build rules to include context_util, builtin_op_data.h
and builtin_ops.h
3. Sync from upstream manually

TFLM is replacing GetInput/GetOutput api with more informative
micro_context->
AllocateTempXxx/DeallocateTempXxx api for better readability and better
temporary buffer auditing.

See go/tflm-pairing-allocatetemp-with-deallocatetemp for more info

common.c is renamed to common.cc in upstream
github.com/tensorflow/tensorflow/commit/848e84c5a3acda31847457cbd52742436e024984

Hence, change the name to sync it properly

BUG=#407

* Add tensor_utils header files from TensorFlow Lite

* Removed tensor_utils_common.h and added new file lstm_cell.h

tensor_utils_common.h is absorbed into portable_tensor_utils.h
in http://cl/428845263 and lstm_cell.h is separated from
reference_ops.h in http://cl/428639888 and refactored in
http://cl/428808334 for TFLM.

* Support building custom ops

This is backport of internal cl/24778552 in order to support building
custom op from tflite_micro by default.

BUG=https://b/278725942

* Remove empty changes

* Update the ethosu-core-driver version.

* Specify Arm Ethos-U version.

The new version of ethos-u-core-driver requires the Ethos-U version to be specified.
Add ETHOSU_ARCH as a variable to ethosu.inc and specify "u55" as the version for the
Arm Corstone-300 target.

* Update the ethos-u kernel to match new driver.

Update the ethosu.cc with a call to ethosu_invoke_v3.

Temporarily disable the global default enforcement of pairing of AllocateTempXxx/DeallocateTemp  (#908)

* Temporarily disable the global enforcement of pairing of AllocateTemp/DeallocateTempXxx

Temporarily disable the global enforcement of pairing of AllocateTemp/DeallocateTempXxx
because there are some internal test that is using KernelRunner.

BUG=https://b/217818824

* Disable default global enforcing of pair of AllocateTempXxx/DeallocateTemp

* Revert xtensa svdf change

* Clean up GetInput/GetOutput api usage in squeeze, transpose, strided_slice op

Clean up api usage in squeeze, transpose, strided_slice op by replacing
GetInput/GetOutput with AllocateTempXXX/DeallocateTempXXX in micro
context api in squeeze, transpose, strided_slice op

Additionally, squeeze and transpose is using TfLiteTensor in Invoke,  which
is againts the recommendation and unnecessary. Replace them with the usage of
TfLiteEvalTensor.

This is a continuation of pr #894 to improve both readability and safety of getting tensors.

The next step is to clean the GetInput/GetOutput in test_helpers.cc
before enforcing the pair of AllocateTempXXX and DeallocateTemp globally.

BUG=https://b/209453859

* Fix bluepill test: need to explictly use int32_t so that the right templated typeToTfLiteType is chosen and return the right type

* Remove redundant include

* Clean GetInput/GetOutput api usage in test_helpers

* Enforce the pairing of AllocateTemp/DeallocateTemp for all kernel tests

* Fix svdf/full_connected in cmsis_nn variant and conv in xtensa variant

* Fix xtensa

* Fix depthwise_conv in xtensa

* Fix xtensa again

* Fix compilation. Xtensa local test pass

* Fix xtensa/full_connected not showing up locally

* update cmsis_nn svdf

* Fix pooling for hifi5

* hif5 errors seen only on server

* Fix hifi5 again

* Reshape op - replace slow byte-wise copy with memcpy()

memcpy() usually comes optimized for a DSP/Micro and offers superior
performance.

BUG=217301557

* Add newline

* Now add the newline at the right place.

* Add #include <cstring> for memcpy()

BUG=217301557

* Add files from TfLite

Added batch_matmul.h and tensor_utils_common.h that are needed for the BATCH_MATMUL operator.

* Convert Colab hello_world training to local Python script.

bug=#892

Use tensorflow 2.7.0

Add assertion checks.
Add loss and MAE limits.
Add pip install of modules.

Add shell script to compare models.

* Fix formatting errors not caught by VSCode.

Replace (almost) all kernel's GetInput/GetOutput with AllocateTempXXx and DeallocateTempXxx micro context api (#894)

* Replace GetInput/GetOutput with micro context api

* Replace GetInput/GetOutput in kernels with micro_context api. Ther are three kernels (strided_slice, squeeze, transpose)that are not changed yet because:
they put the returned value of GetInput/GetOutput in an OpData structure that is persistent.
It is better to have separate change to opdata of those kernels

* Fix corner case in pad

* Fix cmsis-nn

* Fix xtensa, cmsis_nn, hexagon

When upgrading the docker container, we see new format
fix/check on existing python file. That is because we did not
fix yapf version. This PR sets the yapf version to the
latest 0.32.0, which is what the latest container is using

BUG=https://issuetracker.google.com/216670232

* Create pad integration tests for SEANet.

Modify generation script to include PAD operator and fix issue where shapes were being modified. Size > 2 is still valid since all weights for conv and transpose_conv have shapes with length 4.

* Revert format changes removing newlines in generat_per_layer_tests.py

* Add unit tests for 16-bit tanh and logistic kernels

* Disable int16 logistic test for xtensa

Xtensa optimized logistic kernel does not support int16 yet.
Disable the test for it for now.

* Use reference int16 logistic for xtensa and update test accordingly

* Document source of test vectors and expected results

* adding pandas and matplotlib

* updating container tag to latest

* fixing formatting issues that have been slipping through older ci setup

Add AllocateTempInputTensor to replace GetInput() and Add AllocateTempOutputTensor to replace GetOutput() (#885)

This corresonds to internal cl/424648139

Add more informative api AllocateTempInputTensor to replace GetInput()
and AllocateTempOutputTensor to replace GetOutput(). These two new API
call out the fact that what GetInput and GetOutput returns are in
temporary buffer and  need to call DeallocateTempTensor() afterwards.

IF operator is the first OP to use these APIs.
