Auto merge of #5272 - Phlosioneer:5211-missing-size-hints, r=matklad

Implement size_hint for some iterators

This PR implements size_hints for `Deps`, `DepsNotReplaced`, and `Members`.
These size_hints are used extensively by cargo to allocate Vecs.

`Deps`, `DepsNotReplaced`, and `RcVecIter` also now implement `ExactSizeIterator`.

Closes #5211
