Implement model construction for the array extension of sequences (#7815)
The array solver is still not usable, the only remaining changes from seqArray are to connect the array solver to the strings theory solver via the strategy + the regressions.

api: Add Solver::mkUnresolvedSort(). (#7817)
This adds a function to create unresolved sorts for mutually recursive
datatpes. This function creates an uninterpreted sort if the arity of
the unresolved sort is 0, and a sort constructor sort otherwise.

Fix get-model when sort constructors are present (#7828)
Fixes a spurious error on kind benchmarks.
Note that we don't properly handle instantiated sort constructors currently, which I believe need to be handled as declared sorts when calling getModel.
