Failure building DNNE on ARM64 legs

[MichalStrehovsky]

Seen failure in native AOT and jitstress runs, not clear why mainline CI doesn't hit it. Here's jitstress: https://dev.azure.com/dnceng-public/public/_build/results?buildId=1370894&view=logs&jobId=9097dc03-f269-564e-13ab-e3241c6d3ff2&j=9097dc03-f269-564e-13ab-e3241c6d3ff2&t=c5623a8c-64c0-58ae-fdde-1827619f67c9

Looks like this line is the issue: https://github.com/AaronRobinsonMSFT/DNNE/blob/2a810d0b4cbde7190169739678e3f13462f39e57/src/msbuild/DNNE.BuildTasks/Windows.cs#L56-L57

Weird that runtime doesn't hit it - maybe the tests built on x64 and run on arm64?

I'm adding exclusions for this to #126848 to make this less urgent.
