smt: add smt.relevancy.watch_filter toggle for the watch-list filter

Browse source 
Make the relevancy_propagator watch-list membership filter (m_is_watched)
runtime-toggleable via a new boolean parameter smt.relevancy.watch_filter
(default true). When false, get_watches() always probes m_watches, giving
the pre-filter behavior. This enables A/B performance comparison of the
same binary (filter on vs off) under the Ramon benchmark harness.

Behavior-preserving either way: verified identical results on QF_LIA with
the filter on and off.
