crypto/x509: use netip.ParseAddr in VerifyHostname for IPv6 zones

net.ParseIP returns nil for zone-scoped IPv6 addresses (e.g.
fe80::1%eth0), causing VerifyHostname to fall through to DNS name
matching instead of IP matching. Switch to netip.ParseAddr which
handles zone IDs correctly; AsSlice() returns the zone-free byte
representation for comparison against certificate SANs.

Fixes #79719
