test-coroutine: add performance test for nesting
The performance test will also check for nesting. It will do a certain quantity of cycles, and each of one will do a depth nesting process. This is useful for benchmarking the creation of coroutines, given that nesting is creation-intensive (and the other perf test does not benchmark that).
