Wasm AOT crashes during ILStrip (.NET 10 / Windows) and in the IntegrationTests

[FreyLuis]

There seem to be two separate issues with Wasm AOT.

Issue 1: During the ILStrip step, it crashes because *_compiled_methods.txt files are missing. I could only reproduce this with .NET 10 / Windows. Both .NET 8 / Windows and .NET 10 / Linux work fine.

minimal example

public static class Program
{
    private const string _dotnetMonikerString = "net10.0";
    private const RuntimeMoniker _dotnetMoniker = RuntimeMoniker.WasmNet10_0;

    public static void Main()
    {
        CleanupPreviousJob();

        var wasmToolchain = WasmToolchain.From(new NetCoreAppSettings(_dotnetMonikerString, _dotnetMonikerString, "Wasm", aotCompilerMode: MonoAotCompilerMode.wasm));

        var config = DefaultConfig.Instance.AddJob(Job.Dry.WithRuntime(new WasmRuntime(_dotnetMonikerString, _dotnetMoniker, "wasm", aot: true, "v8")).WithToolchain(wasmToolchain));

        config.WithOption(ConfigOptions.LogBuildOutput, true);
        config.WithOption(ConfigOptions.GenerateMSBuildBinLog, true);
        config.WithOption(ConfigOptions.KeepBenchmarkFiles, true);

        BenchmarkRunner.Run<SampleBench>(config);
    }

    public static void CleanupPreviousJob()
    {
        var dir = Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location);
        foreach (var item in Directory.GetDirectories(dir!, "WasmBenchmark-Dry-*"))
            Directory.Delete(item, true);
    }
}

I have also attached msbuild binlogs.

Issue 2: With the changes in #3020 the Wasm AOT IntegrationTests are crashing while trying to aot xunit.runner.visualstudio.testadapter.dll.
This is reproducible on Windows and Linux.
