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`.)

feat: Array.mem: Avoid DecidableEq, set up decreasing_trivial (#2774) 
The notation `a ∈ as` for Arrays was previously only defined with
`DecidableEq` on the elements, for (apparently) no good reason. This
drops this requirements (by using `a ∈ as.data`), and simplifies a bunch
of proofs by simply lifting the corresponding proof from lists.

Also, `sizeOf_lt_of_mem` was defined, but not set up to be picked up by
`decreasing_trivial` in the same way that the corresponding List lemma
was set up, so this adds the tactic setup.

The definition for `a ∈ as` is intentionally not defeq to `a ∈ as.data`
so that the termination tactics for Arrays don’t spuriously apply when
recursing through lists.

1abd5cc665 chore: add simp option unfoldPartialApp 
It is not being used yet, but we need to add it before solving issue #2042.
Reason: bootstrapping.

and `cbv` tactic for improving its performance.

fix: delete Measure and SizeOfRef (#2275) 
* move Measure to Nat namespace

We could (and maybe should) also move various other declarations to namespaces, like measure. However, measure seems to be used a lot in termination_by statements, so that requires other fixes as well. Measure seems to be almost unused

* fix

* delete Measure and SizeOfRef instead
