Save PLY point clouds in all capture samples

[SatjaSivcev]

For C++, C#, Python, all capture samples save to ZDF, which is not possible for Halcon (HDevelop). Then, we instead should save to PLY by default.

A function (Halcon procedure) to save ply is to be made that can be reused for conversion to simplify the code. Use the code from the CaptureSavePLY. The function should include the following lines:

zivid-halcon-samples/source/hdev/Camera/Basic/CaptureSavePLY.hdev

Lines 48 to 84 in 236c07d

	<l>write_object_model_3d (ObjectModel3D, 'ply', 'Zivid3DPLY.ply', ['invert_normals'], ['true'])</l>

with one exception: visualization should not be included.

That function is to be included in samples with capture (same ones in cpp that save to zdf), so Capture.hdev, CaptureHDR.hdev, etc.
