Merge pull request #29101 from asmorkalov:as/geometry_module

Browse Source 
Moved geometry transformations from imgproc to 3d, future geometry module #29101

The first step of 2d geometry operations migration to the future geometry module.
I created 2d.hpp to isolate the moved functions for now. I propose to create geometry.hpp when the module is renamed and include all things there.

OpenCV contrib: https://github.com/opencv/opencv_contrib/pull/4126
