[ip6] new methods in Header and add unit test (#7561)

Browse Source 
This commit adds new methods in `Ip6::Header` to get and set Traffic
Class, Flow fields. It also updates and renames some of the existing
methods. This commit also adds a unit test `test_ip6_header` to
validate the IPv6 header parsing and preparation.
