[Feat] Point Properties: Normalization

[SharonIV0x86]

Title: Normalize a point vector to a unit vector
Description:
Implement a normalize() function for the Point class to return a normalized version of the point vector (unit vector). Handle the case where the magnitude is zero.
Function Signature:

Point<T, Dim> normalize() const;

File: Point.hpp
Class: Point
Acceptance Criteria:

• Add the normalize() function to the Point class.

• Ensure the function works for points of any dimension.

• Handle the case where the magnitude is zero by throwing an exception or returning a meaningful error.

• Write unit tests to verify the correctness of the implementation.
