ethdev: add IPv4/IPv6 ECN header rewrite action

This patch introduces the IPv4/IPv6 ECN modify field support, and
adds the testpmd CLI commands support.

Usage:
	modify_field op set dst_type ipv4_ecn src_type ...

For example:

flow create 0 ingress group 1 pattern eth / ipv4 /  end actions
	modify_field op set dst_type ipv4_ecn src_type value src_value
	0x03 width 2 / queue index 0 / end
