Added mouse api interface

[KiritoDv]

This PR Adds a mouse support api for future port implementations

API:

Ship::Coords Window::GetMousePos();
Ship::Coords Window::GetMouseDelta();
Ship::CoordsF Window::GetMouseWheel();
bool Window::GetMouseState(Ship::MouseBtn btn);
void Window::SetMouseCapture(bool capture);
bool Window::IsMouseCaptured();

Overall this all seems reasonable. What would be wonderful to see is a proof-of-concept of a port using it (possibly updating HarbourMasters/2ship2harkinian#870 to use it)

The main issue with HarbourMasters/2ship2harkinian#870 is that it directly changes Controller.cpp in LUS to write relative mouse to gyro.

@garrettjoecox any chance you have ideas on how to accomplish what HarbourMasters/2ship2harkinian#870 is doing using this PR as a base?

@briaguya-ai https://github.com/HarbourMasters/2ship2harkinian/pull/870/files Have another look. Not beautiful (just applying it to the gyro) but I think the LUS side of this is fine, will be up to the port to determine what to do with the input.

that's perfect for a proof of concept! just knowing this API works and nothing else is needed/has to be changed on the LUS side is what i was hoping to learn!

I tested this on mk64 and it worked. I did not test all the features. But mouse tracking was good.
