Auto merge of #106790 - the8472:rawvec-niche, r=scottmcm
add more niches to rawvec Previously RawVec only had a single niche in its `NonNull` pointer. With this change it now has `isize::MAX` niches since half the value-space of the capacity field is never needed, we can't have a capacity larger than isize::MAX.
