doc(array,vec): add notes about side effects when empty-initializing
Copying some context from a conversation in the Rust discord:
* Both `vec![T; 0]` and `[T; 0]` are syntactically valid, and produce empty containers of their respective types
* Both *also* have side effects:
```rust
fn side_effect() -> String {
println!("side effect!");
"foo".into()
}
fn main() {
println!("before!");
let x = vec![side_effect(); 0];
let y = [side_effect(); 0];
println!("{:?}, {:?}", x, y);
}
```
produces:
```
before!
side effect!
side effect!
[], []
```
This PR just adds two small notes to each's documentation, warning users that side effects can occur.
I've also submitted a clippy proposal: rust-lang/rust-clippy#6439
