Different Eventloops on windows can now be explored

[Vizonex]

What do these changes do?

These Changes unlock the ability to use different event-loops with Windows in the future. This will allow users to explore other ideas and workarounds to maybe even Subclass the ProactorEventLoop to get no-event threads instances to work. Winloop no longer needs to be imported to aiodns thus saving a bit of time with checking and configuring. I moved it to a function mainly to be simulated but I can always move these parts back to the make_channel function if needed.

Are there changes in behavior for the user?

Users will no longer be locked to using winloop or the SelectorEventLoop if a windows operating system is being used. Importing winloop to aiodns inside the dns resolver no longer needs to be done. I changed the wording of the error message. Now it says it requires any eventloop but the ProactorEventLoop aiodns cannot use ProactorEventLoop on Windows if event-threads cant be utilized implying that winloop or the SelectorEventLoop or Any Custom EventLoops instead.

whoops I did not take ProactorEventLoop attribute into account. When I get back from other activities I will fix this immediately.

Thank goodness I got all of that done. That took longer than it needed to to solve.

Thanks. Once we sort out https://github.com/aio-libs/aiodns/issues/175 we can move this forward
