[ONNX] Aligned behavior of ONNX Frontend function Relu-6, 13, 14 with original framework

[Phantom65536]

#20564

1. Differences between opsets: 1–6 involves a legacy attribute in opset 1; 6–13 and 13–14 involve differences in input types.
2. Implemented relu support for opsets 6, 13, and 14 in relu.cpp.
3. There were changes in ops_bridge.cpp, so I don't think relu functions need to be registered there. I couldn't find another file where other onnx frontend operations are registered, nor did I find any header files in src/frontends/onnx/frontend/src/op, so I didn’t make changes there.
4. Created .prototxt test models for ReLU in src/frontends/onnx/test/models.
5. Added ReLU-related test cases in onnx_import.in.cpp. All test cases passed for IE_CPU and INTERPRETER.
6. Didn’t find any xfailed tests related to this issue or ReLU.

hey @Phantom65536
clang format checks failed, could you fix it, please?

[Phantom65536]

I've fixed the clang formattings.

I already ran clang-format on the modified files so I'm not sure why the clang-format checks failed.
