This is exactly as originally landed in #95129,
but now the minimal Z3 version was increased to meet this change in #96682.

This patch is a functional change.

As a result of this patch, individual Z3 queries in refutation will be
bound by 300ms. Every report equivalence class will be processed in at
most 1 second.
The heuristic should have only really marginal observable impact -
except for the cases when we had big report eqclasses with long-running
(15s) Z3 queries, where previously CSA effectively halted. After this
patch, CSA will tackle such extreme cases as well.
