Fix jit32 perf and throughput testing

Fix jit32 perf and throughput testing

For jit32, we need to download the compatjit to make sure we are using a
jit32 build, not legacy backend (which is what is built when we run a
regular build out of coreclr). This change updates the groovy scripting to
pull down the jit nuget package that contains compatjit.

Until the packaging is fixed (dotnet/coreclr#9991), we are defaulting to the last
package that packaged compatjit along with clrjit.
