Produce intermediate json output for coverage (#8252)
This splits the generation of coverage information into two steps, generating an intermediate json file. This allows further tooling to used this json information: we plan to check whether the APIs (and their tests) are complete by looking at their code coverage within the cpp api.

Do not expand APPLY_SELECTOR (#8174)
Currently we expand (sel_C_n x) to (ite (is-C x) (sel_C_n_total x) (uf x)) during ppRewrite. This introduces ITEs very eagerly and moreover is not necessary since we do congruence over selectors.
This makes it so that we don't do this expansion. The code changes to use APPLY_SELECTOR everywhere instead of APPLY_SELECTOR_TOTAL, which can be deleted in a followup PR. It makes some of the datatype utilities more robust and independent of options.
This required changing one detail of the sygus solver to not do evaluation unfolding in cases where a selector chain was wrongly applied, as this now will not rewrite to a constant.

Eliminate shadowing in the quantifiers rewriter (#8244)
Fixes #8227.
Recently, we allowed unevaluatable terms to be in the range of substitutions solved during preprocess.
In very rare cases, it may be the case that a quantified formula is substituted into itself, e.g.:
forall x. P(x, b) where b was solved to be forall x. P(x, c)
This leads to forall x. P(x, forall x. P(x, c)) where x is shadowed.
To resolve this issue, we eliminate shadowing in the quantifiers rewriter, e.g. we rewrite the above to forall x. P(x, forall y. P(y, c)).
An alternative solution would be to ensure we use capture avoiding substitutions, but this severely complicates our usage of substitutions throughout the preprocessor / proof system.
This PR also eliminates some dead code in the quantifiers rewriter.

Try harder to show that a RAN is rational (#8230)
We try to rewrite real algebraic numbers to rationals. This is important to, e.g., allow the linear solver to see rational constants at all. Refining real algebraic numbers is done lazily, and (almost) any operation may trigger a refinement that makes libpoly realize it actually is rational. Thus, even the mere act of creating a node out of a real algebraic number may do this (it hashes it).
This PR thus introduces a fixed-point loop into the RAN node constructor that defends against this case.
Fixes #8226.

Previously the concern was that this would interfere with e.g. quantifiers + non-linear. However, our strategy is now fair wrt other theories as we send lemmas at LAST_CALL effort, and is properly restricted by the nl-ext mode.
Moreover, this option increases our ability to solve problems (instead of saying "unknown") significantly, even for quantified logics like UFNIA.
