Auto merge of #33124 - sfackler:kill-ipv6-only, r=alexcrichton

Remove IPV6_V6ONLY functionality

These settings can only be adjusted before bind time, which doesn't make
sense in the current set of functionality. These methods are stable, but
haven't hit a stable release yet.

Closes #33052

[breaking-change]

r? @alexcrichton

Will also need a backport to the beta.
