4eeefd72 - Add shader key validation step in WebGPU CI pipeline (#24243)

Add shader key validation step in WebGPU CI pipeline (#24243) ### Description This PR adds a shader key validation step to the WebGPU CI pipeline. The shader key validation works in this way: - first, run onnxruntime_test_all with verbose logging, dumping the logs into a file - then, parse the file and found WebGPU EP program logs. The log contains the following information: - the shader cache key - the corresponding shader code The script will aggregate those information and make sure for each cache key, the corresponding shader code must be consistent. To make the validation work, this PR also modified a few things: - set the locale of `std::wclog` to ".UTF-8" to support Unicode characters. Otherwise the logger will fail and no longer output future logs. A fix is submitted in PR #24237 but there is a concern if this may potentially break some users. Setting inside onnxruntime_test_all is pretty safe. - re-enable the WebGPU device auto collect which was introduced in https://github.com/microsoft/onnxruntime/pull/24115. Now we have a better way to detect cache key inconsistency. ### Next Step The newly added test is marked as `continue-on-error: true`, which means even if it failed it does not block the CI pipeline. We should fix those failures one-by-one and eventually the test should pass. then we can remove the `continue-on-error: true` flag.
