Allow SyGuS subsolver to be reused in incremental mode (#7785)
This allows SyGuS subsolvers to be called multiple times to produce solutions for a given set of SyGuS constraints using a new command check-synth-next.
By default, the SyGuS subsolver will generate a new solution for each successive check-synth.
This simplifies the internal SyGuS solver in several ways for this purpose. It also ensures that solutions are cached; current master may recompute solutions in the same state more than once if asked, which is no longer the case.
This completes our support for incremental SyGuS.

[proofs] Alethe: Fix Bug in Finalize (#7746)
Assumptions in Alethe are printed as (or F1 ... Fn) but should be treated as if they are printed as (cl (or F1 ... Fn)). Thus, if in the post visit it is checked whether an additional or step is needed this has to be treated as a special case.

Allow sygus in incremental mode (#7756)
This allows the basic use of SyGuS in incremental mode, where constraints can be pushed/popped.
It does not yet support getting multiple solutions for the same set of constraints, which will require more significant changes.

Make data structures in relevance manager SAT-context dependent (#7733)
This PR significantly improves the quality of values in get-difficulty. It fixes several bugs related to get-difficulty, including over-pruning values in ProofManager, and not tracking explanations for certain literals. It also improves performance by tracking justifications in relevance manager in a SAT-context dependent manner.
This is to support difficulty measurements based on lemmas sent at STANDARD effort.
It also adds 2 simple regressions.
A further PR will further improve the quality by being more careful about the relationships between literals and the assertions that entail that they are relevant.

Towards support for incremental sygus (#7736)
This makes several key changes to smt::SygusSolver in preparation for incremental mode.
The key idea is to use a subsolver that:
may take multiple check-sat commands for an encoded synthesis conjecture
does not push/pop
is reconstructed when the SyGuS conjecture becomes stale.
This is motivated by 2 use cases of incremental SyGuS:
Where constraints are push/pop, in which case we should start from scratch, since the SyGuS solver uses symmetry breaking techniques that become unsound when new constraints are added.
Where multiple solutions are needed for the same set of constraints, in which the state of the subsolver should be preserved.
This functionality is still guarded by an exception.
A follow up PR will make several further changes to allow for the above use cases.

Add bitwise option to IntBlaster (#7721)
This is part of a series of PRs by @yoni206 to add full int-blasting support to the master branch of `cvc5`. This adds support for the bitwise encoding to `IntBlaster`. Future PRs would unify the `bv2int` and `IntBlaster` helper functions.

Disable option regression for competition build (#7751)
This disables a regression that checks the didyoumean output for an invalid output on competition builds. On competition builds, we simply print "unknown" instead of shown any exceptions.

Use unique_ptr instead of raw pointers (#7749)
This PR fixes a memory leak when invalid values are supplied to the stream options err, in or out. Whenever opening the stream would fail, we throw an exception and the created (though not properly opened) stream is leaked.
We now properly wrap the streams in unqiue_ptrs directly on creation.
