auto merge of #14307 : kballard/rust/vim_prelude_mutablecloneablevector, r=cmr

Add slice::MutableCloneableVector to the prelude. It's the only slice
trait that's currently missing.

Update rust.vim to match the latest prelude and current set of keywords.
Also teach it to handle box placement expressions specially.
