feat: encode let_fun using a letFun function (#2973) 
Switches from encoding `let_fun` using an annotated `(fun x : t => b) v`
expression to a function application `letFun v (fun x : t => b)`.

fix: Option.getD eagerly evaluates dflt (#3043) 
Reported [on
Zulip](https://leanprover.zulipchat.com/#narrow/stream/348111-std4/topic/Panics.20in.20Std.2EHashMap.2Efind!/near/406872395).
The `dflt` argument of `Option.getD` is not evaluated lazily, as the
documentation says, because even after `macro_inline` the expression
```lean
match opt, dflt with
| some x, _ => x
| none, e => e
```
still has the semantics of evaluating `dflt` when `opt` is `some x`.

doc: mention dite in ite docstring (#2924) 
Some beginners have trouble finding the `if h : c then t else e`
(`dite`) version of `ite`. This augments `ite`'s docstring to mention
the dependent version.

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`.)

870de844dc chore: annotate relevant monadic code with [alwaysInline] 
TODO: after we delete old code generator, we should replace
`@[alwaysInline, inline]` with `@[alwaysInline]`.

Remainder: we want the old code generator to ignore `@[alwaysInline]`
annotations, in particular, the new ones on `instance` commands that
are actually annotations for the instance methods.

767bda2c28 chore: preparing to change the semantics of @[inline] instance 
In the new code generator, we are going to lambda lift the instance
methods before saving the code at the end of the base phase. The goal is to make instance
ligth weight and cheap to inline. The anotation `@[inline]` is going
to be an annotation for the lambda lifted methods.
