Feature Request: Add support for netip Addr and AddrPort value types

[database64128]

In Go 1.18, new read/write methods were added to net.UDPConn to take advantage of the new netip value types. I updated my code to use these new methods. But the expected savings fail to manifest, because for debug and error logs I had to pass the returned netip.AddrPort value to zap as Stringer, which leads the Go compiler to allocate them on the heap.

It'd be nice if zap has support for these new types. But I could see the difficulty of retrofitting these types into the Field struct.

I added netip support in my logging lib in phuslu/log@7a25b6a

I think it worth a look.
