Rollup merge of #104435 - scottmcm:iter-repeat-n, r=thomcc
`VecDeque::resize` should re-use the buffer in the passed-in element Today it always copies it for *every* appended element, but one of those clones is avoidable. This adds `iter::repeat_n` (https://github.com/rust-lang/rust/issues/104434) as the primitive needed to do this. If this PR is acceptable, I'll also use this in `Vec` rather than its custom `ExtendElement` type & infrastructure that is harder to share between multiple different containers: https://github.com/rust-lang/rust/blob/101e1822c3e54e63996c8aaa014d55716f3937eb/library/alloc/src/vec/mod.rs#L2479-L2492
