This change introduces support for MLDv2/IGMPv3. Note that this change
does not yet introduce APIs to perform source filtering so SSM is not
yet supported. Also note that this change does not yet coalesce records
in a report as that will come in a follow-up.
Updates #8346

This change has significant performance implications. bufferv2 is reference
counted and pooled, which alleviates heap/GC pressure. Below are the results
from running the iperf benchmark.

It did introduce overhead, mainly at the bridge between pkg/buffer and
VectorisedView, the ExtractVV method. Once endpoints start migrating away from
VV, this overhead will be gone.
Updates #2404
PiperOrigin-RevId: 373651666
One of the preparation to decouple underlying buffer implementation.
There are still some methods that tie to VectorisedView, and they will be
changed gradually in later CLs.
This CL also introduce a new ICMPv6ChecksumParams to replace long list of
parameters when calling ICMPv6Checksum, aiming to be more descriptive.

- Pass a PacketBuffer directly instead of releaseCB
- No longer pass a VectorisedView, which is included in the PacketBuffer
- Make it an error if data size is not equal to (last - first + 1)
- Set the callback for the reassembly timeout on NewFragmentation
