fix: expression tree elaborator for relations now localizes error messages to the LHS or RHS (#3442) 
Added `withRef` when processing the LHS or RHS. Without this, in an
expression such as `true = ()` the entire expression would be
highlighted with "type mismatch, `()` has type `Unit` but is expected to
have type `Bool`". Now the error is localized to `()`.

This behavior was pointed out [on
Zulip](https://leanprover.zulipchat.com/#narrow/stream/270676-lean4/topic/error.20location.20bug/near/422665805).

feat: Nat.mul_mod (#3582) 
Proves
`Nat.mod_mul : x % (a * b) = x % a + a * (x / a % b)` and
`Nat.mod_pow_succ : x % b ^ (k + 1) = x % b ^ k + b ^ k * ((x / b ^ k) %
b)`, helpful for bitblasting.

perf: match_expr join points (#3580) 
We use `let_delayed` to elaborate `match_expr` join points, which
elaborate the body of the `let` before its value. Thus, there is a
difference between:
- `let_delayed f (x : Expr) := <val>; <body>`
- `let_delayed f := fun (x : Expr) => <val>; <body>`

In the latter, when `<body>` is elaborated, the elaborator does not know
that `f` takes an argument of type `Expr`, and that `f` is a function.
Before this commit ensures the former representation is used.

refactor: simplify some nomatch with nofun (#3564) 
and also don’t wrap `nomatch` with `False.elim`; it is not necessary, as
`nomatch` already inhabits any type.

fix: load references asynchronously (#3552) 
In v4.6.0, there was a significant regression in initial server startup
performance because the .ilean files got bigger in #3082 and we load the
information stored in all .ilean files synchronously when the server
starts up.

This PR makes this loading asynchronous. The trade-off is that requests
that are issued right after the initial server start when the references
are not fully loaded yet may yield incomplete results.

Benchmark for this in a separate PR soon after this one.
