Following up #5928 , updates the syntax for `omega` and `solve_by_elim`
and restores the syntax quotations in their implementations.
Following up #5898 , uses the new tactic syntax in the library, replacing
all uses of `(config := ...)`.

feat: relate for loops over List with foldlM ( #5913 )
...
There are many more lemmas about `foldlM`, so this may be useful for
reasoning about for loops by transforming them into folds.
The transformation includes accounting for monad effects, but does have
a mild performance difference in that short-circuiting on
`ForInStep.done` is replaced by traversing the rest of the list with a
noop.

chore: remove duplicated ForIn instances ( #5892 )
...
I'd previously added an instance from `ForIn'` to `ForIn`, but this then
caused some non-defeq duplication. It seems fine to just remove the
concrete `ForIn` instances in cases where the `ForIn'` instance exists
too. We can even remove a number of type-specific lemmas in favour of
the general ones.

feat: if support and more in bv_decide ( #5855 )

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!

chore: simplify signature of Array.mapIdx ( #5749 )
...
This PR simplifies the signature of `Array.mapIdx`, to take a function
`f : Nat \to \a \to \b` rather than a function `f : Fin as.size \to \a
\to \b`.
Lean doesn't actually use the extra generality anywhere (so in fact this
change *simplifies* all the call sites of `Array.mapIdx`, since we no
longer need to throw away the proof).
This change would make the function signature equivalent to
`List.mapIdx`, hence making it easier to write verification lemmas.
We keep the original behaviour as `Array.mapFinIdx`.
