Add some helper functions to dump 4D tensors to help debugging.
Example to use it:
(1) Change DUMP_TENSOR_LEVEL from 0 to 2 in
contrib_ops/cpu/utils/debug_macros.h to enable dumping. Without
enabling, the dumping code will not be built into ORT binary.
(2) Add a few lines to dump tensors like
```
DUMP_CPU_TENSOR_INIT();
DUMP_CPU_TENSOR("tensor name", tensor_data, dim0, dim1, dim2, dim3);
```
Changes:
- [x] Add functions to dump 4D int32/int64/float/half tensors in CPU
- [x] Add functions to dump 4D int32/int64 tensors in CUDA
- [x] Change namespace (remove .transformers from namespace, and move
files to utils directory)
### Description
Run clang-format in CI. Formatted all c/c++, objective-c/c++ files.
Excluded
```
'onnxruntime/core/mlas/**',
'onnxruntime/contrib_ops/cuda/bert/tensorrt_fused_multihead_attention/**',
```
because they contain assembly or is data heavy
### Motivation and Context
Coding style consistency
Optimize top 1 computation in greedysearch.
For vocabulary size 50k on A100,
- batch size 1: from 220us to 10.4us.
- batch size 4, from 230us to 11.5us.
For generation of 50 tokens for example, it saves 50*0.2ms = 10ms.
### Description
<!-- Describe your changes. -->
1. add an optional input to pass in seed
2. two UTs. one for top_p=0.5, another for top_p=0.01(create greedy
search result, in convert_generation.py)
3. fix a bug in cpu kernel
