```
std.mem.asBytes: fix footgun when passing non-single pointer

I was just bitten by this footgun, where I actually wanted
`sliceAsBytes` but unintentionally used `asBytes`, which in practice
ignored all but the first element. Just add a comptime assertion to
trigger a compile error in this case.

```
