Support Client Migration (Client Side)

[masa-koz]

Description

This PR adds the support of Client Migration (Client SIde). Fix #1946.

This pull request includes significant changes to the QUIC connection ID management and introduces a new feature for manual connection ID generation for testing purposes. The most important changes include the replacement of QUIC_CID_HASH_ENTRY with QUIC_CID_SLIST_ENTRY to register connection IDs into more than one bindings, the addition of new APIs to add/remove local address in client, and the introduction of a conditional compilation feature for manual connection ID generation.

Added QuicConnOpenNewPath and QuicConnOpenNewPaths are to manage opening new paths for a connection. These functions will be called when Destination Connection ID is available for sending PATH_CHALLENGE.

Testing

I've added two test.

• Basic/WithProbePathArgs.ProbePath/*
• Basic/WithMigrationArgs.Migration/*

Documentation

In this PR, the following two Connection level Parameters will be added.

• QUIC_PARAM_CONN_ADD_LOCAL_ADDRESS
• QUIC_PARAM_CONN_REMOVE_LOCAL_ADDRESS

@masa-koz Are you going to have time to add the requested extra tests? If not, do you mind if we add them later?
