Merge #10793: Changing &var[0] to var.data()
592404f03 Changing &vec[0] to vec.data(), what 9804 missed (MeshCollider)

Pull request description:

  This just continues the work of https://github.com/bitcoin/bitcoin/pull/9804

  Modifies a lot of `&vector[]`'s to `vector.data()`'s across all the files including tests, just the stuff that 9804 missed
