Yuki Okushi f26f201d42 Rollup merge of #75085 - lzutao:ip_union, r=cuviper ...

Transmute big endian `s6_addr` and `[u16; 8]`

The old code already made the assumption to reinterpret
`Ipv6Addr` as `[u16; 8]`.

Glibc, Linux, FreeBSD, Win32 all makes this assumption.
The main motivation of using union it to better optimize code.
Godbolt: https://rust.godbolt.org/z/b4bGvo
Const is introducing unsafe when transmuting.
