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 conflicts with fact that all multiplicities are non-negative.
Another error was that the difference_remove inference rule didn't consider the negative case for (count e B)
(= (count e (difference_remove A B)) (ite (= (count e B) 0) (count e A) 0))) ; not enough
(= (count e (difference_remove A B)) (ite (<= (count e B) 0) (count e A) 0))) ; the right rule

This PR fixes the proof generated for the nonlinear monomial bounds check lemmas. In some cases, it implies an equality (multiplied by a monomial) not from the equality but from the two weak inequalities. We now properly detect this special case and add a rather involved proof.

Remove options::X__numValues (#7419)
This PR removes yet another special purpose options detail that is only used in a single place: X__numValues currently holds the number of modes for an option, that is the number of elements of the respective enums. It is solely used to obtain the size of the std::bitset used to store the flags passed to the -o option. However, it can easily be replaced using the last mode.
This PR also improves a bit on options-related documentation.

Properly guard proof construction for STRINGS_EXTF_EQ_REW (#7519)
Fixes one of the issues raised in cvc5/cvc5-projects#331, the other involves missing skolem definitions for str.replace_all_re @4tXJ7f .
This properly guards cases of proof reconstruction for STRINGS_EXTF_EQ_REW where an intermediate step in the proof checker inferring something stronger than what it is asked to prove. In particular, substitution+rewriting is more powerful than congruence+rewriting:
s=x => (str.<= t s) ----> (= r "") since (str.<= t "") ----> (= r "")
but additionally:
(str.<= t s) * { s -> x } ----> true, which is possible if s occurs as a subterm of t.
The proof reconstruction for STRINGS_EXTF_EQ_REW is not precise as there are several other aspects that are not covered. After this PR, we properly guard and fail to reconstruct if the above issue arises, so the assertion failure will not throw.
