asyncio: Document return values of AbstractEventLoop.remove_{reader,writer}

[bdarnell]

Documentation

According to python/typeshed#7042, AbstractEventLoop.remove_{reader,writer} return a bool, but there is no indication of this in the documentation for these methods. These return values need to be documented so that subclass implementors can know how to implement them appropriately.
