[Tests] Audit tests annotated with `DotNetIgnore` or other ignored categories

[pjcollins]

Now that we are no longer running some classic tests in CI, we should review the MSBuild tests that are ignored in the One .NET test runs to make sure we aren't missing any coverage.

On a quick search, the DeleteBinObjTests fixture and potentially other tests in BuildTest.cs may be worth updating to run against .NET.

#8163 addresses most of this, we will only need to look at the HybridAOT, MonoSymbolicate, and StaticProject categories in a future PR.
