Enable IPv6 WriteHeaderIncludedPacket
Allow writing an IPv6 packet where the IPv6 header is a provided by
the user.
* Introduce an error to let callers know a header is malformed.
We previously useed tcpip.ErrInvalidOptionValue but that did not seem
appropriate for generic malformed header errors.
* Populate network header in WriteHeaderIncludedPacket
IPv4's implementation of WriteHeaderIncludedPacket did not previously
populate the packet buffer's network header. This change fixes that.
Fixes #4527
Test: ip_test.TestWriteHeaderIncludedPacket
