fixes #1202 More than 120 threads was started by NNG
This introduces a new CMake option, NNG_MAX_TASKQ_THREADS, with
a default value of 16. The number of taskq workers will generally
be calculated as vcpu * 2. This new value, if not zero, sets an
upper bound. Note that the value should be at least two, in order
to ensure no deadlocks occur.
