Add AssertSoft String overload for Java Api (#5475) 
This adds a String overload for AssertSoft.
Previously only integer weights could have been used,
limiting the user. With Strings the user can now use
e.g. Java's BigInteger class converted to a String instead.

That the bug went away is a fluke. It wasnt fixed.
It is in pb-preprocess, an essentially unused tactic. The special subsumption resolution rule wasn't accounting for membership of all variables.

Add an alternative to unit-subsume-simplify
It is called solver-subsumption
It does a little more than unit-subsume-simplify and also uses a different decomposition algorithm for clauses.
It removes redundant constraints and simplifies clauses in a single pass.
A possible use of this tactic is in isolation where the maximal number of conflicts
(smt.conflicts_max, sat.conflicts_max) are bounded. For simpler formulas full solver calls may be still feasible.

Remove size argument in OCaml's Z3.mk_re_intersect (#5383) 
* Remove size argument in OCaml's `Z3.mk_re_intersect`

Passing the size as argument is unnecessary in OCaml, and that argument is abridged in all similar `Seq` functions. This applies the same pattern.

* Enable the ocaml documentation in Seq.

Turn all the comments into proper documentation comments.

Force in-lining auxiliary functions so that model values can be used by SPACER to retrieve counter-examples. This fixes the issue of terminating without a trace. It does not address inefficiency involved with invoking satisfiability checks to retrieve models during trace construction.

@veanes
mk_bool_app_helper has a bug:
When it simplifies a disjunction or conjunction of regex membership constraints of the form (and (str.in_re "" R) (str.in_re x Q))
then the first term (str.in_re "" R) is omitted in the result.
You have a test here
3da9d91866/src/ast/rewriter/seq_rewriter.cpp (L438)
that means a regex membership with empty first argument is not put in the two buffers with membership/non-membership.
It isn't put into new_args either because the test bypasses these
