Adds std::format support for math types

Adds `std::formatter` specializations for `Mat`, `Vector2`, `Vector3`, and `Vector4` types, enabling the use of `std::format` for these types.

This simplifies formatting and printing of these mathematical objects, improving code readability and consistency.

Also adds a hash function specialization for Vector3.
