Add static methods to create RayQueryParameters

[KoBeWi]

The intersect_ray() method was changed to take single PhysicsRayQueryParameters object instead of several arguments. This is great for flexibility, but not for convenience, as a one-line is turned into a 4-liner (in the minimal case). So I added some static methods with most common parameters to quickly create query objects.

Convenient, and useful for --convert-3to4 project conversion. I think implementing the _init constructor would also be a reasonable alternative, but I don't have strong feelings about it.

Is there any reason for swapped collision_mask & excludes arguments? It used to be from/to/excludes/mask

[KoBeWi]

I don't know about excludes, but given what masks are usually used for, the default value makes little sense and you always want it customized. In my project, out of 23 uses of intersect_ray(), all of them change the mask, but only 2 use excludes. So I just moved the more commonly used argument earlier in the list.
