Auto merge of #50739 - gnzlbg:vec_reserve, r=sfackler
Switch Vec from doubling size on growth to using RawVec's reserve

On growth, Vec does not require to exactly double its size for correctness,
like, for example, VecDeque does.

Using reserve instead better expresses this intent. It also allows to reuse
Excess capacity on growth and for better growth-policies to be provided by
RawVec.
