Alexander Smorkalov 40ddc700aa Merge pull request #29230 from asmorkalov:as/move_undistort
Inverted imgproc-geometry dependency and moved more functions to geometry #29230

Fixes: https://github.com/opencv/opencv/issues/20267
Continues: https://github.com/opencv/opencv/pull/29175

OpenCV Contrib: https://github.com/opencv/opencv_contrib/pull/4137
OpenCV Extra: https://github.com/opencv/opencv_extra/pull/1377

Summary:
- LSD returned back to imgproc
- drawing functions moved to imgproc
- undistort image and related perf-pixel functions moved to imgproc
- moments moved to geometry
- estimateXXXtransform moved to geometry

After the patch the geometry module depends on code and Flann and may be used everywhere without potential circular dependencies
