The perf wasm leg is not supposed to run on PR (and was just moved to outerloop). Since none of the code in this PR affects anything in the perf wasm leg, I'm going to merge this once the Mono test legs that are currently running are green. |

This fixes errors from crossgenning sparse vtable types on non-Windows platforms. Running crossgen on crossgen2 causes crossgen to try to readytorun some sparse vtables in Microsoft.DiaSymReader.dll. This change fixes crossgen to ignore these members and not error out on Linux (same behavior as Windows).
This PR also adds a test that tests sparse vtables on Windows and tests the sparse vtable crossgenning on all platforms.
