It is often useful to know the capacity of a
Vec. For example, the deepsize crate (DeepSizeOf trait) provides an estimation of the size of aVecin memory. Currently, FrozenVec does not expose acapacity()function, which makes it difficult to account for the allocated heap memory of the underlying storage. This PR add a function toFrozenVec<T>that return the capacity of the underlyingVec.
