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

Rename 'user' to 'user_solver' #5586 (#5587) 
Issue #5586 reported that Android builds (targetting, e.g., x86) failed
to compile due to a conflict between:

* `struct user` in `sys/user.h`; and
* `namespace user` in z3's `user_solver.h`

This issue is resolved by renaming `namespace user` to `namespace
user_solver` (matching the header name) to avoid this conflict.
