Auto merge of #79100 - a1phyr:better_assert_eq, r=m-ou-se
...
Improve assert_eq! and assert_ne!
This PR improves `assert_eq!` and `assert_ne!` by moving the panicking code in an external function.
It does not change the fast path, but the move of the formatting in the cold path (the panic) may have a positive effect on in instruction cache use and with inlining.
Moreover, the use of trait objects instead of generic may improve compile times for `assert_eq!`-heavy code.

Document that `assert!` format arguments are evaluated lazily
It can be useful to do some computation in `assert!` format arguments, in order to get better error messages. For example:
```rust
assert!(
some_condition,
"The state is invalid. Details: {}",
expensive_call_to_get_debugging_info(),
);
```
It seems like `assert!` only evaluates the format arguments if the assertion fails, which is useful but doesn't appear to be documented anywhere. This PR documents the behavior and adds some tests.
