Fix half precision gemm test accumulation error (#14842)
### Description

Half precision gemm test requirement relaxation

### Motivation and Context

Most CPUs does not support mixed precision accumulation, only mul & add
fuse. As a result, different striding on the K dimension may lead to
rounding error. Accumulation of these rounding error maybe very
significant. So setting an approximation ratio does NOT always work.
What's more, a relaxed test condition may hide real implementation
problem. So this is only a compromised fix.

More rigorous tests require manual efforts:
1. Change the K stride of the kernel under test to be 16.
2. Force the K stride of the fp16 kernel to 16
3. Change the test oracle to be exact match.
4. Pass this test and then change it back :-(.

ONNX Runtime is a cross-platform inference and training machine-learning accelerator.

ONNX Runtime inference can enable faster customer experiences and lower costs, supporting models from deep learning frameworks such as PyTorch and TensorFlow/Keras as well as classical machine learning libraries such as scikit-learn, LightGBM, XGBoost, etc. ONNX Runtime is compatible with different hardware, drivers, and operating systems, and provides optimal performance by leveraging hardware accelerators where applicable alongside graph optimizations and transforms.
