Initial stateless reset detection

Backport the stateless reset patch to AOSP (current
version of quiche is 0.14.0) so that we don't need to
wait until the patch is released to a quiche version
newer than 0.16.0 (currently, the latest version is 0.16.0).

This patch is slightly modified because the type of
stateless_reset_token is different (In 0.14.0 the
type is Option<Vec<u8>>; in 0.16.0 the type is
Option<u128>).

Test: cd packages/modules/DnsResolver && atest
Test: cd external/rust/crates/quiche && atest
Test: 1. Applied ag/20124672 to DnsResolver
      2. Ran dnschk every 5 minutes for 1 hour
      3. Checked the log:
        a. Confirmed that some stateless reset packets were received
        b. Confirmed that DNS queries fallback'ed to DoT immediately
           after DnsResolver received stateless reset packets
