deps: update to ngtcp2 0.8.1 and nghttp3 0.7.0

[tniessen]

This updates the two existing QUIC dependencies to the latest tagged versions as described in #44619.

This obsoletes two commits from @jasnell's #44325 in order to make the QUIC PR simpler to review (with his permission).

• deps: update ngtcp2 and nghttp3
• Fixup ngtcp2 sources list

---

@jasnell This is not the same update as in your PR. Instead, I opted for the latest tagged versions so that we won't have to play catch-up immediately afterwards. Unfortunately, it does not compile cleanly. As far as I can tell, the only compilation error is the use of ngtcp2_pkt_decode_version_cid, and this patch appears to resolve the compilation problem:

(However, it could be that the semantics of the return value changed... I don't understand the ngtcp2 API yet.)

I'm marking this as blocked until #44619 lands because this PR is based on those instructions.
