Purpose

This PR is a followup PR to the base PR(#10548).

1. Removed the failing FirstClassFunctions as that is not being supported.
2. The test VerifyIronPythonLoadedAssemblies was failing on self-serve because the IronPython.dll was also being copied into the "nodes" folder and the parent bin folder. This was causing an issue when the test was trying to load the dll from multiple locations. After this change, the IronPython.dll is just copied to the parent bin folder and the test passes.
