Enforce `QuicConnectionMigrationManager` and `QuicSpdyClientSessionWithMigration` to use QuicForceBlockablePacketWriter during construction.

And add a new subclass `QuicClientPathValidationContext` to enforce that client-side path validation contexts provide a `QuicForceBlockablePacketWriter`.

With both enforcement, remove unsafe static_cast from QuicConnection::writer() to `QuicForceBlockablePacketWriter` in `QuicConnectionMigrationManager` by caching the `QuicForceBlockablePacketWriter` object in QuicSpdyClientSessionWithMigration whenever there are path changes.
