Use AsyncTaskCache in ValueTask.AsTask()

We can avoid task allocations for common values by using the same task cache that async methods do.  This is important to avoid allocations in certain cases when switching from Task-returning to ValueTask-returning methods.  If at some point we change Task.FromResult to use the same cache, this can be reverted.
