[Bug]: Question: Are cores from `IBuildEngine9.RequestCores` expected to be released between batched task invocations?

### Issue Description

[EmitBundleBase](https://github.com/dotnet/runtime/blob/542983327f61706b2ed07583601861846361364b/src/tasks/MonoTargetsTasks/EmitBundleTask/EmitBundleBase.cs#L153-L154) task in `dotnet/runtime` uses `IBuildEngine9.RequestCores`, and depends on these being released when the task's `Execute` is done. But if the task is batched, then for any subsequent invocations the task gets blocked on `RequestCores`. If I use `ReleaseCores` before returning from `Execute`, then it works fine.

Is this the expected behavior?

### Steps to Reproduce
