[REQ] need a uninit_task parameter for thread_pool

[debuggingbug]

Describe the new feature

Now only has init_task, better has uninit_task.

Code example

BS::thread_pool task_thread_{1,
                             [] {
                                 ::CoInitializeEx(nullptr, COINIT_APARTMENTTHREADED);
                             },
                             [] { CoUninitialize(); }};
