Auto merge of #45446 - leodasvacas:remove-libcollections, r=alexcrichton

Remove deprecated `collections` crate. The real `collections` was merged with `alloc`, this facade was introduced [in this PR](#42720) to give `#[no_std]` users time to adapt. This was done at least two cycles ago, now we can consider removing it for good.
