This PR changes `bv_decide`'s configuration from lots of `set_option` to
an elaborated config like `simp` or `omega`. The notable exception is
`sat.solver` which is still a `set_option` such that users can configure
a custom SAT solver globally for an entire project or file. Additionally
it introduces the ability to set `maxSteps` for the simp preprocessing
run through the new config.
The latter feature was requested by people using `bv_decide` on SMTLIB
which has ginormous terms that exceed the default.
Using the same strategy as #5852 this provides `bv_decide` support for
`Bool` and `BitVec` ifs
this in turn instantly enables support for:
- `sdiv`
- `smod`
- `abs`
and thus closes our last discrepancies to QF_BV!
... while at it also call `trivial` to close goals that can be trivially
closed.
