ENH: Use std::vector instead of raw new[] in QuadEdgeMesh test

Replace raw `new PointIdentifier[]` with `std::vector<PointIdentifier>`
and `std::iota` in TestCellInterface and TestQECellInterface. This
resolves core.CallAndMessage scan-build findings where the analyzer
could not verify value-initialization of raw new[] arrays.
