Fix exclusion criteria for codatatype model values (#7546)
This fixes codatatype model value construction.
Model construction for codatatypes is non-standard since it requires analyzing whether (possibly recursively defined) terms are alpha equivalent to others during model construction. This is currently handled as a special case within the theory model builder. (This should eventually be moved somewhere more appropriate via a new callback to theory).
This fixes the criteria which was too permissive about which values can be used in models. We now exclude values that match the skeleton of representative codatatype terms. Previously we additionally required that the terms were bisimilar.
Fixes #4851.

Eliminate a level of nesting of traversals in theory preprocessing (#7345)
This simplifies the theory preprocessor so that it does not rely on the term formula removal to do a nested traversal. Instead, it only relies on its "runCurrent" method.
Notice that this PR essentially replaces TheoryPreprocessor's theoryPreprocess method with TermFormulaRemoval's runInternal method, while adding the required call to rewriteWithProof and preprocessWithProof as post-rewrites. This is far simpler than the previous method, which invoked nested traversals using TermFormulaRemoval::run.
There are two things that will be improved in follow up PRs:
The initial full rewrite step in the theory preprocessor can be merged into the main traversal of theory preprocess (I believe this is why we are slower on nec benchmark than we were previously),
We should eliminate the traversal methods from TermFormulaRemoval altogether, as they are now subsumed by the theory preprocessors main traversal. This will require refactoring how "early ITE removal" works, as this is the only user now of TermFormulaRemoval::run.
Note we should probably performance test this change.
This incidentally fixes #6973, as the previous theory preprocessing code was to blame for that issue.

[FP] Do not assert that model has shared term (#7585)
Fixes #7569. Currently, the FP solver asserts that
m->hasTerm(sharedTerm) is always true for the real term in the
conversion from real to floating-point value. This is not necessarily
the case because the arithmetic solver computes values for the variables
in the shared terms but not necessarily for the terms themselves. This
commit removes the assertion and instead relies on the fact that a later
assertion checks that m->getValue(sharedTerm).isConst(), which is the
property that we are actually interested in.
