[jdk21u-dev] RFR: 8282726: java/net/vthread/BlockingSocketOps.java timeout/hang intermittently on Windows

I backport this for parity with 21.0.8-oracle.

Resolved Poller.java because "8318422: Allow poller threads be virtual threads" is not in 21.
I extended the change to registerAsync(int fdVal) which is not in head.
