BLI: add use_threading parameter to parallel_invoke
`parallel_invoke` allows executing functions on separate threads.
However, creating tasks in tbb has a measurable amount of overhead.
Therefore, it can be benefitial to disable parallelization when
the amount of work done per function is small.
See D15539 for some benchmark results.
