This PR updates remainder of the TFLM examples, all the kernels and integration tests to remove the usage of ErrorReporter as per the changes made to the TFLM Framework API in https://github.com/tensorflow/tflite-micro/pull/1415; replaces TF_LITE_REPORT_ERROR with MicroPrintf.

* Enable -Wmissing-field-initializers and update all registration
references

In https://github.com/tensorflow/tflite-micro/pull/1082/, we disabled
the compiler error as a workaround for a successful upstream sync from
TFLite. This PR re-enables the error after addressing all errors. A new
`RegisterOp` API is added, and all prior TfLiteRegistration struct
initializations are updated to use the new API. At the minimum, this
ensures that such additions in future will only require an update to
RegisterOp if TFLM doesn't use that field.

BUG=b/230507399

* Added new RegisterOpWithFree for LSTM

* Remove LSTM Free

* Changed inline to normal function to save code size

* Changed inline to normal function to save code size

* Replace cmsis_nn static initialization with RegisterOp

* Removed extra code

* Add dropped namespace in hard_swish

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

* Add virtual destructor.

Some platforms generate warnings/errors that a class that has
virtual functions should have virtual destructor

BUG=observe in internal presubmit

* Fix ReadVariable, AssignVariable and VarHandle to use the micro_context api to get graph

Since PR #819, using GetExecutionPath is no longer the right way to get
graph.  These kernels miss the required change in PR #819.
This PR address this issue.

Additionally, this PR includes some changes to make some internal build
system happy such as avoid casting nullptr to reference

BUG=observe failure in internal example test

* Fix auto merge error manually
