Auto merge of #74512 - LukasKalbertodt:debloat-copy-from-slice, r=KodrAus
Put panic code path from `copy_from_slice` into cold function
The previous `assert_eq` generated quite some code, which is especially problematic when this call is inlined. This commit also slightly improves the panic message from:
assertion failed: `(left == right)`
left: `3`,
right: `2`: destination and source slices have different lengths
...to:
source slice length (2) does not match destination slice length (3)
You can see the code bloat in assembly [here](https://rust.godbolt.org/z/74a3qo).
