Make all remaining methods of `std::net::Ipv4Addr` const

Makes the following methods of `std::net::Ipv4Addr` unstable const under the `const_ipv4` feature:
 - `is_global`
 - `is_reserved`
 - `is_broadcast`
 - `to_ipv6_compatible`
 - `to_ipv6_mapped`

This results in all methods of `Ipv4Addr` being const.

Also adds tests for these methods in a const context.
