Added Raymath binding + Initial examples

- Added Raymath.cs binding. Raylib.cs depends on this since they both share some types.
- Bindings moved into source directly.
- Inital examples port alot of syntax still needs to be fixed.
- Couldn't get cppsharp to work correctly so using a custom generator(WIP).
