Rollup merge of #50233 - mark-i-m:const_vec, r=kennytm
Make `Vec::new` a `const fn`
`RawVec::empty/_in` are a hack. They're there because `if size_of::<T> == 0 { !0 } else { 0 }` is not allowed in `const` yet. However, because `RawVec` is unstable, the `empty/empty_in` constructors can be removed when #49146 is done...
