Foundation Classes, math_DoubleTab - Rework to NCollection container (#607)

Foundation Classes, math_DoubleTab - Rework to NCollection container (#607)

- Refactors `math_DoubleTab` to use `NCollection_Array2` as its underlying container
- Eemoves the old C‐array implementation, and updates collection classes to improve move semantics and bounds manipulation.
- Rework `math_DoubleTab` to wrap `NCollection_Array2`, with buffer optimization for small sizes
- Enhance `NCollection_Array2` and `NCollection_Array1` with proper move semantics and bound‐updating methods
- Remove legacy `.lxx`/`.cxx` implementations, add tests and update CMake file lists
