Move API focused C++ samples to snippets #25252
Clean Samples #25006
This PR removes 39 outdated C++ samples from the project, as part of an effort to keep the codebase clean and focused on current best practices.
OBJ and PLY loaders extention to support texture coordinates and difused colors #25221
### This PR changes
* Texture coordinates support added to `loadMesh()` and `saveMesh()`
* `loadMesh()` changes its behavior: all vertex attribute arrays (vertex coordinates, colors, normals, texture coordinates) now have the same size and same-index corresponce
- This makes sense for OBJ files where vertex attribute arrays are independent from each other and are randomly accessed when defining faces
- Looks like this behavior may also happen in some PLY files; however, it is not implemented until we encounter such files in a wild nature
- At the same time `loadPointCloud()` keeps its behavior and loads vertex attributes as they are given in the file
* PLY loader supports synonyms for the properties: `diffuse_red`, `diffuse_green` and `diffuse_blue` along with `red`, `green` and `blue`
* `std::vector<cv::Vec3i>` supported as an index array type
* Colors are loaded as [0, 1] floats instead of uchars
- Since colors are usually saved as floats, internal conversion to uchar at loading significantly drops accuracy
- Performing uchar conversion does not always makes sense and can be performed by a user if they needs it
* PLY loading fixed: wrong offset ruined x coordinate
* Python tests added for `loadPointCloud` and `loadMesh`

[GSoC] Update octree methods and create frames for PCC #23985
## PR for GSoC Point Cloud Compression
[Issue for GSoC 2023](https://github.com/opencv/opencv/issues/23624)
* We are **updating the Octree method create() by using OctreeKey**: Through voxelization, directly calculate the leaf nodes that the point cloud belongs to, and omit the judgment whether the point cloud is in the range when inserted. The index of the child node is calculated by bit operation.
* We are also **introducing a new header file pcc.h (Point Cloud Compression) with API framework**.
* We added tests for restoring point clouds from an octree.
* Currently, the features related to octree creation and point cloud compression are part of the internal API, which means they are not directly accessible to users. However, our plan for the future is to **include only the 'PointCloudCompression' class in the 'opencv2/3d.hpp' header file**. This will provide an interface for utilizing the point cloud compression functionality.
The previous PR of this was closed due to repo name conflicts, therefore we resubmitted in this PR.

Connected PR in contrib: [#3388@contrib](https://github.com/opencv/opencv_contrib/pull/3388)
### Changes
OK, now this is more Odometry-related PR than Volume-related. Anyway,
* `Volume` class gets wrapped
* The same was done for helper classes like `VolumeSettings`, `OdometryFrame` and `OdometrySettings`
* `OdometryFrame` constructor signature changed to more convenient where depth goes on 1st place, RGB image on 2nd.
This works better for depth-only `Odometry` algorithms.
* `OdometryFrame` is checked for amount of pyramid layers inside `Odometry::compute()`
* `Odometry` was fully wrapped + more docs added
* Added Python tests for `Odometry`, `OdometryFrame` and `Volume`
* Added Python sample for `Volume`
* Minor fixes including better var names

Corresponding contrib PR: #3382@contrib
Changes
- Volume::raycast(): camera intrinsics can be explicitly passed to the function. If not, the ones from current volume settings are used
- getVolumeDimensions() renamed to getVolumeStrides() because they are strides actually
- TSDF tests: OpenCLStatusRevert and parametrized fixture
- ColorTSDF::integrate(): extra RGB projector is redundant, removed
- Minor changes
This PR contains:
- a new property enableGrowth which controls should the HashTSDF be extended during integration by adding new volume units or not
- a new method getBoundingBox which calculates the size of currently occupied data
- a set of tests to check that new functionality
- a fix for TSDF GPU reset (data is correctly zeroed now using floatToTsdf() function)
minor changes
There's a bug which appears when volume pose contains non-trivial rotation.
It results in wrong depth integration which can be observed during raycasting
or points/normals export.
- This PR fixes the bug for both CPU and OpenCL
- There is a reproducer for the bug
- The copy behavior of VolumeSettings fixed (now copy constructor creates a deep copy)
- Minor changes (e.g. unused vars removed)
