feat: replace ite and dite shortcircuit theorems with simproc
...
Motivation: better `simp` cache behavior. Recall that `simp` cache
uses `dischargeDepth`.

feat: add pre simp lemmas for if-then-else terms
...
See new test for example that takes exponential time without new simp
theorems.
TODO: replace auxiliary theorems with simprocs as soon as we implement them.

feat: find Decidable instances via unification ( #2816 )
...
Because `Decidable` carries data,
when writing `@[simp]` lemmas which include a `Decidable` instance on the LHS,
it is best to use `{_ : Decidable p}` rather than `[Decidable p]`
so that non-canonical instances can be found via unification rather than
typeclass search.
(Previously this behaviour was often being hidden by the default `decide :=
true` in `simp`.)
