check: extend ProcessBlock callback with error handler

[AnnaShaleva]

For anti-MEV extension it's possible that some commits carry invalid share which is impossible to check at the commit verification level. In this case node should collect some more commits.

The general idea is similar to PreBlock processing behaviour. Draft until it's properly tested on NeoX side.
