winemac: Wrap performing requests from background threads in an autorelease pool.

Cocoa manages an autorelease pool on the main thread, but it only drains it
when it processes an event.  Our requests come through a run loop source, which
doesn't count as an event.  So, autoreleased objects can accumulate when the
app is not being interacted with.
