87d4ce2659 working on #5614 
there are some different sources for the performance regression illustrated by the example. The mitigations will be enabled separately:
- m_bv_to_propagate is too expensive
- lp_bound_propagator misses equalities in two different ways:
   - it resets row checks after backtracking even though they could still propagate
   - it misses equalities for fixed rows when the fixed constant value does not correspond to a fixed variable.

FYI @levnach

fix grouping for latest doxygen (#5626) 
Since doxygen 1.8.16, opening and closing a group must not be done as
C comment but as doxygen command. In other words, not one but two
asterisk characters are required so that doxygen finds a group.

tweak GC in OCaml bindings (#5600) 
* feat(api/ml): use custom block hints to guide the GC

this forces the GC to collect garbage when a few _large_ objects
(solver, etc.) are dead. The current code would let arbitrarily many
such objects die and not trigger a GC (which would have to come from
OCaml code instead)

* tuning

* try to use caml_alloc_custom_mem with fake sizes

* try to fix leak by explicitly finalizing OCaml context

* chore: use more recent ubuntu for azure CI

* remove finalizer causing segfault in example
