ot::Ip6::Address::IsIp4Mapped() const method

Indicates whether or not the IPv6 address follows the IPv4-mapped format. An IPv4-mapped IPv6 address consists of an 80-bit prefix of zeros, the next 16 bits set to ones, and the remaining, least-significant 32 bits contain the IPv4 address, e.g., `::ffff:192.0.2.128` representing `192.0.2.128` IPv4 address.
