Support ALLOW_HALF_CLOSURE channel option on Unix domain socket. (#8932)
Motivation: Since DomainSocketChannel is a DuplexChannel, which be able to shutdown input or output individually on demands, but ALLOW_HALF_CLOSURE channel option has not been supported yet. I thought this could be a missing feature of Unix domain socket, so here the PR for it. Modifications: 1. Added allHalfClosure property both in EpollDomainSocketChannelConfig and KQueueDomainSocketChannelConfig, 2. Enabled isAllowHalfClosure method of native channel to support domain channel config, 3. Created EpollDomainSocketShutdownOutputByPeerTest and KQueueDomainSocketShutdownOutputByPeerTest to verify the change. Result: ALLOW_HALF_CLOSURE channel option can be set with DomainSocketChannel, and no more warning of Unknown channel option 'ALLOW_HALF_CLOSURE'.
