Revert "Revert "Add utilities to create IPv6 ICMP messages.""

This reverts commit 405c1bfca93fa25ae1616a93ee6e2a1f76d87d1e.

Bug: 168868607
Test: atest NetworkStackIntegrationTest

Reason for revert: Roll forward the previous change and try to merge it one by one instead of using the topic, which should avoid the build broken on the sc-dev branch due to the deferred auto-merge process.
