[AIX] test-suites failure fixes

[Ranjit Ranjan (ranjitshs)]

Description

This PR is to fix some of the test case failures mentioned in #25790

1. cmake/onnxruntime_unittests.cmake
   To fix the onnxruntime_shared_lib_test crash
2. include/onnxruntime/core/providers/utils/ort_graph_to_proto.h
   Added method for handling external data.
   For fixing , EpGraphTest.SerializeToProto_ConstantOfShape , EpGraphTest.SerializeToProto_Mnist, EpGraphTest.SerializeToProto_InputModelHasExternalIni
3. onnxruntime/core/framework/tensorprotoutils.cc
   For fixing many test failures , related to float16 or Int16 type.
4. onnxruntime/test/framework/endian_test.cc
   For fixing, ConvertRawDataInTensorProtoTest.FloatData and ConvertRawDataInTensorProtoTest.Int32Data

Motivation and Context

To fix the AIX (Big endian) related test failures.

FYI.
Could you please review this PR and let me know your inputs.

Also, please trigger CI workflows for this PR.

[Ranjit Ranjan (ranjitshs)]

Also, for handling external data I have added ConvertExternalData() in ort_graph_to_proto.h which will be called in case be BE system Before writing data to file.

With this change, all tests for onnxruntime_ep_graph_test are passing.

Let me know if any further comment in this PR . Can we close this PR if no further comments.

I will spend time for rest failures and will raise separate PR.

1: [  FAILED  ] FlatbufferUtilsTest.ExternalWriteReadWithLoadInitializers
1: [  FAILED  ] InternalTestingEP.TestSaveAndLoadOrtModel
1: [  FAILED  ] OrtModelOnlyTests.ValidateOrtFormatModelDoesNotRunOptimizersInFullBuild

[Dmitri Smirnov (yuslepukhin)]

Added more comments, this also needs to be rebased.

Will address these comments in next commit. Thanks for reviewing it.

I see in some OS Ci's is failing with below . I will change and make this method as API . Wondering why it's not hit in all OS.
Could be strict compiler flags or latest compiler is used where it's failing.

/mnt/vss/_work/onnxruntime/onnxruntime/include/onnxruntime/core/providers/utils/ort_graph_to_proto.h:720:20: error: 'static' function 'ConvertExternalData' declared in header file should be declared 'static inline' [-Werror,-Wunneeded-internal-declaration]

To not put any dependency on ort_graph_to_proto.h, I am thinking to add the required BE related method in this header file as static method . I am testing my changes and will upload for review.

I was going through CI failures . There are some python related import failures, not related to this PR.

In windows debug X64, I see below . But same is passing in release mode.
I don't have windows for analysing it. Any suggestion .
I am thinking to put from line num 762 to 775 under if !defined(_WIN32)

Hi Dmitri Smirnov (@yuslepukhin)
I have updated the code to fix windows debug build warning mentioned above.
Could you please run CI workflow .

I see some new wanring(converted to error) under mainly WIN workflows.

Update the code to handle unreferenced function parameters
Once you get time, please trigger CI once. Hope, this time it will go through. sorry for inconvenience

[Dmitri Smirnov (yuslepukhin)]

You can comment out the names of the unreferenced params
