Add rewrite for array selects of chain of stores of a same value (#6526) 
* Add rewrite for array selects of chain of stores of a same value

Example:
```smt
(declare-fun mem () (Array (_ BitVec 4) (_ BitVec 4)))
(declare-const x (_ BitVec 4))
(declare-const y (_ BitVec 4))
; simplifies to #x1
(simplify (select (store (store (store mem #x1 #x1) y #x1) x #x1) #x1))
```

* Update array_rewriter.cpp

f6d411d54b experimental feature to access congruence closure of SimpleSolver 
This update includes an experimental feature to access a congruence closure data-structure after search.
It comes with several caveats as pre-processing is free to eliminate terms. It is therefore necessary to use a solver that does not eliminate the terms you want to track for congruence of. This is partially addressed by using SimpleSolver or incremental mode solving.

```python
from z3 import *
s = SimpleSolver()
x, y, z = Ints('x y z')
s.add(x == y)
s.add(y == z)
s.check()
print(s.root(x), s.root(y), s.root(z))
print(s.next(x), s.next(y), s.next(z))
```
