Revert to ProactorEventLoop

Tested the change and magically there isn't set_wakeup_fd errors

Can you give me a little background on this (or point me to some if it's out there already)? And which version of windows do you see the set_wakeup_fd errors?

So on previous bombsquad version you switced to using WindowsSelectorEventLoop due to the error set_wakeup_fd only works in the main thread, on test build 1.7.37 i reverted the change to the default windows event loop which is the ProactorEventLoop
and found that it works fine without the set_wakeup_fd errors.
I made this pull request to revert the loop to use the default which is the ProactorEventLoop so in future we detect what causes the errors maybe debug and fix it.
