Summary:
Don't use IOBufQueue for most operations in mvfst and use BufQueue instead. Since BufQueue did not support a splitAtMost, added it in instead.
The only place that we still use IOBufQueue is in crypto because fizz still requires it

Summary:
Get rid of IObufQueue usage in the PacketBuilder and replace it with a vanilla IOBuf.
This requires replacing QueueAppender with something else as well, so this diff adds a new class call BufAppender which does exactly the same things as a QueueAppender.
Having a BufAppender will allow us to avoid cloning the stream buffer in the future and avoid a clone during the write path.

Summary:
`IOBufQueue` has some facilities for fast appending to the tail. This is not useful for us in the retransmission buffer usecase, and probably not at all. Flushing the tail cache from the `IOBufQueue` is expensive when we have to shuffle around the retransmission buffer queue on removal.
This diff replaces `IOBufQueue` with a bespoke version that only has some of the functionality.
This also changes the dependent peek APIs to use `IOBuf`s directly.
