The SAT solver may associate, to the result of a resolution, a lower assertion
level than the current one. To be able to produce proofs to such clauses, we
extend the SAT proof manager to track which resolution results were
optimized. Then, when the SAT solver pops, the manager is notified and stores
the proofs for these optimized clauses, so that they can be reinserted when the
user context is popped. The latter is handled by the SAT proof manager's
OptClauseManager attribute.

Fixes cvc5/cvc5-projects#494.
With this fix, we now properly consider terms that belong to other theories that are of set type, e.g. (select x (as set.universe (Set RoundingMode)) in this example to be "variables" according to the theory of sets procedure.
The benchmark is unsat because there are 5 rounding modes and we are selecting an index in a sequence storing "false" at the first 6 indices.

Fixes for skolem definition management (#8301)
Fixes two issues with how we manage skolem definitions (used for tracking which assertions are relevant for the decision engine).
First, the theory proxy must be notified of skolem definitions before we have assertions involving them, or else hasSkolems is wrong. This was previously done incorrectly for lemmas. This PR changes the order in PropEngine::assertLemmasInternal.
Second, skolem definitions are local to a solver instance and should not be managed by attributes, moreover they are user-context dependent. This changes it to a local user-context dependent map in Skolem.
Fixes #8296.

Introduce new splitting inference in sets + cardinality (#8290)
Fixes cvc5/cvc5-projects#486.
This introduces a new strategy which splits on whether Venn regions are equal to each other before it splits them into sub-Venn regions.
The issue in the above was caused by a case where the sets solver decided to make 2 Venn regions of the same equivalence class disjoint. By splitting on their equality first, this should introduce the necessary information to discover this is a conflict (via disequality witnessing). It should also be more efficient since we introduce new set terms lazier.

Add algorithm for finding pairs of paths in a node trie (#8286)
This is in preparation for cleaning our implementation of care graph computations.
Right now, UF, datatypes, sets, and strings all have copy/pasted versions of an algorithm that creates an index of operators and run the algorithm in the PR for computing care graphs.
Followup PRs will extend the theory interface and add an instance of this class for computing care graphs. Then, we will add optimized care graph computation for bags (which is missing right now), and then perhaps revisit arrays, which appears to have issues in its computeCareGraph method.

Improvements for sygus query generation (#8224)
Makes the two sygus query generators have a common base class, which makes it so that they both can dump queries.
Also fixes the expression miner to use user-level sygus terms, otherwise we can make queries using invalid internal terms, e.g. SEQ_NTH_OOB skolem.
The majority of the diff in this PR is moving query_generator to query_generator_sample_sat, and adding a basic version of query generation.
