feat: lemmas relating Array.findX and List.findX (#5985)
This PR relates the operations `findSomeM?`, `findM?`, `findSome?`, and
`find?` on `Array` with the corresponding operations on `List`, and also
provides simp lemmas for the `Array` operations `findSomeRevM?`,
`findRevM?`, `findSomeRev?`, `findRev?` (in terms of `reverse` and the
usual forward find operations).

feat: interactions between List.foldX and List.filterX (#5984)
This PR adds lemmas for `List` for the interactions between {`foldl`,
`foldr`, `foldlM`, `foldlrM`} and {`filter`, `filterMap`}.

chore: upstream List.insertIdx from Batteries, lemmas from Mathlib, and revise lemmas (#5969)
To follow, connecting this to `Array.insertAt` (and renaming).

feat: List.pmap_eq_self (#5927)
This is a `pmap` analog of
[`List.map_id''`](https://leanprover-community.github.io/mathlib4_docs/Init/Data/List/Lemmas.html#List.map_id'').

feat: add Int16/Int32/Int64 (#5885)
This adds all fixed width integers with the exception of `ssize_t` so
the code is quick to review as everything just behaves the same.

feat: update omega/solve_by_elim to use new tactic syntax, use new tactic syntax (#5932)
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.

…an up BVDecide

- Fix names

  shiftLeft_zero_eq -> shiftLeft_zero
  ushiftRight_zero_eq -> ushiftRight_zero

- Remove duplicate prefixes

  BitVec.mul_zero -> mul_zero
  BitVec.mul_add  -> mul_add

- Adapt BVDecide/Normalize/BitVec by reusing the following functions

  zero_add | add_zero
  and_self
  mul_zero | zero_mul
  shiftLeft_zero | zero_shiftLeft
  sshiftRight_zero | zero_sshiftRight
  ushiftRight_zero | zero_ushiftRight

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!
