Doc: Move remaining examples to Data Visualization & 3D

They're 3D, so let's better collect all 3D examples here.

This also includes moving a highlighted example:
'Qt Quick 3D - Particles 3D Testbed Example'

Pick-to: 6.5 6.6
Task-number: QTBUG-117219
Change-Id: I1960512f91ac4e6b322a0cf699718b1db0cf7b45
