That number grows quadratically with the number of intermediate
certificates in certain pathological cases (for example if they all have
the same Subject) leading to a CPU DoS. Set a fixed budget that should
fit all real world chains, given we only look at intermediates provided
by the peer.
The algorithm can be improved, but that's left for follow-up CLs:
* the cache logic should be reviewed for correctness, as it seems to
override the entire chain with the cached one
* the equality check should compare Subject and public key, not the
whole certificate
* certificates with the right SKID but the wrong Subject should not
be considered, and in particular should not take priority over
certificates with the right Subject
Fixes #29233
