Will Hawkins 7830180dcd runtime: filter i/o async entries using completion key on windows
In the case where a user program requests overlapped I/O directly on a
handlethat is managed by the runtime, it is possible that
runtime.netpoll will attempt to dereference a pointer with an invalid
value. This CL prevents the runtime from accessing the invalid pointer
value by adding a special key to each overlapped I/O operation that it
creates.

Fixes #58870
