Fix a few special cases of projects with command line arguments (#61758)

* Remove CLRTestExecutionArguments from OOMException01

Test entrypoint is parameterless and so it ignores the argument

* The test entrypoint for 347011 is parameterless so the property is ignored

* Remove project-driven command line arguments from the polyrec test

The test just passes a pair of integers that are used as internal
parameters for the test. Refactor the test so that the entrypoint
accepts the parameters as arguments and call it once from Main
the way we used to do based on the CLRTestExecutionArguments.

Thanks

Tomas
