**Details:**
This PR restores the deleted C-API `cvApproxPoly` tests (part of #24957).
I used `cv::pointPolygonTest` to make sure every original point is within the allowed `epsilon` distance to the final approximated polygon rather than calculate the distance to the corresponding line.
**Update:**
Restored `CV_PerimeterTest` *TEST(Imgproc_ContourPerimeter, accuracy)*.
Created a parameterized test for open/closed curves with int/float type shapes. I also added a simple 10x10 square test.
Geometry:Test cleanup - #29753
**co-authored by: @varun-jaiswal17**
### geometry test cleanup
### Removed (dead or unbuildable)
- `test_modelest.cpp` (231 lines, removed entirely): includes `_modelest.h` and subclasses `CvModelEstimator2`,
both of which are gone from the tree, so it cannot compile.
- `test_cameras.cpp:11-207` (197 lines removed): a `#if 0` block, never compiled, holding an older
`cvtest::ArrayTest`-based `CV_ProjectPointsTest` built on the removed C API (`CvMat`, `cvProjectPoints2`). A
live class of the same name derived from `cvtest::BaseTest` follows it and covers strictly more: `Rodrigues`
plus five jacobians against the dead block's two.
### Given real assertions
- `Calib3d_FindFundamentalMat.correctMatches` (`test_fundam.cpp:410`): reverting the solvePoly fix gives -nan /
1.79e+308 and it still passed.

In 5.0 cv::Mat_<bool>::depth() returns CV_Bool instead of CV_8U, so
boundingRect routed boolean masks into pointSetBoundingRect, which expects
a CV_32S/CV_32F point set and threw. CV_Bool is a 1-byte 0/1 mask type, so
handle it like CV_8U/CV_8S via the byte-wise maskBoundingRect path.
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

Homogeneize some calib/3d behavior #29077
- use CV_Check to validate input sizes (thus throwing for invalid inputs)
- return bool to validate a function result
