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.

Nikolaj Bjorner d5c6abe14d #close 5363 
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
3da9d91866/src/ast/rewriter/seq_rewriter.cpp (L485)
