Title: new Ray geometric primitive, Ray->Raycaster rename, move of geometric primitives to src/math

Dealing with issues:

#2729 - Ray3 geometry primitive (first part of splitting current Ray into separate classes)
#2728 - Separate directories for Geometry Primitives and Scene Primitives instead of mixing them in src/core?

Ray has full unit test coverage and all unit tests pass.
