GSoC: Modified PLY reader to support color attribute read/write #23805

* Modified PLY reader to support color attribute read/write
* Fix bugs & Modified OBJ reader for color IO
* Replace with correct test file
* Fix I/O of property [w] in OBJ files

### Pull Request Readiness Checklist

**Merged with https://github.com/opencv/opencv_extra/pull/1075**

[Issue for GSoC 2023](https://github.com/opencv/opencv/issues/23624)
The ply loader in 3D module doesn't support color attribute reading. I modified that to support color attribute reading & writing for the color attribute compression as described in proposal.
