Publish Z3 symbols (#6280)
* WiP: publish symbols for package

* set debugtype to full

* fix internal nuget feed publishing

* Try pipeline github authorization

* Update github service connection

* WiP: try symbol publish in build

* try Z3Prover for GitHub connection

* WiP: collect symbols

* revert symbol type to pdbonly (only portable is not supported for publishing)

* Publish symbols in nightly and release

* Revert this: comment out publish to test release build pipe

* restore publishing

* Turn of index sources to eliminate warning that it is not supported for Github

Nikolaj Bjorner 48b13291d1 add bv-size reduce #6137
- add option smt.bv.reduce_size.
  - it allows to apply incremental pre-processing of bit-vectors by identifying ranges that are known to be constant.
    This rewrite is beneficial, for instance, when bit-vectors are constrained to have many high-level bits set to 0.

Nikolaj Bjorner 1d87592b13 fixes to mod/div elimination
elimination of mod/div should be applied to all occurrences of x under mod/div at the same time. It affects performance and termination to perform elimination on each occurrence since substituting in two new variables for eliminated x doubles the number of variables under other occurrences.

Also generalize inequality resolution to use div.

The new features are still disabled.

Nikolaj Bjorner 03385bf78d improve quantifier elimination for arithmetic
This update changes the handling of mod and adds support for nested div terms.

Simple use cases that are handled using small results are given below.

```
(declare-const x Int)
(declare-const y Int)
(declare-const z Int)
(assert (exists ((x Int)) (and (<= y (* 10 x)) (<= (* 10 x) z))))
(apply qe2)
(reset)

(declare-const y Int)
(assert (exists ((x Int)) (and (> x 0) (= (div x 41) y))))
(apply qe2)
(reset)

(declare-const y Int)
(assert (exists ((x Int)) (= (mod x 41) y)))
(apply qe2)
(reset)
```

The main idea is to introduce definition rows for mod/div terms.
Elimination of variables under mod/div is defined by rewriting the variable to multiples of the mod/divisior and remainder.

The functionality is disabled in this push.
