Objdetect test cleanup - #29741
co-authored by: @Prasadayus
### Given real assertions
| change | reason |
|---|---|
| new `Objdetect_CheckChessboard.accuracy` (`test_checkchessboard.cpp`) | `cv::checkChessboard`'s only validation lived inside a test named `timing`, which aborted at the first of 19 images. The new test iterates all 19 from `chessboard_timing_list.dat` with `SCOPED_TRACE` and `EXPECT_EQ`, so every image is reported instead of stopping at the first mismatch |
| deleted `test_chesscorners_timing.cpp` | what remained after extracting the assertions was a stopwatch — it measured `findChessboardCorners` and asserted nothing about the result |
### Re-enabled - the reason for disabling no longer holds
| test | reason |
|---|---|
| `Charuco.testSeveralBoardsWithCustomIds` (`test_charucodetection.cpp:922`) | disabled by #24338 because 5.x returns charuco corners as `32FC2` rather than `2×32FC1` (#23473). The test never compares shapes: it asserts `expected_corners.total() == c_corners.total() * c_corners.channels()` and then compares `expected_corners.reshape(1, 1)` against `c_corners.reshape(1, 1)` — both flattened to one row, so the channel layout cannot affect the result. The comparison was already made shape-agnostic; only the `DISABLED_` prefix was never removed |

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.
