Rollup merge of #62709 - nhynes:test-maplike-fromiter, r=cuviper

Test that maplike FromIter satisfies uniqueness

This PR adds a simple assertion to the `HashMap` and `HashSet` tests to ensure that uniqueness is satisfied when `FromIter`ing. This is useful for people who want to test their custom type against the Map/Set interfaces since they'll copy the tests wholesale but possibly miss this bug (where _they_ = _me_).
Empowering everyone to build reliable and efficient software.
