Material variants

[LeXXik]

Add a description of all material types in the engine, which ones are supported by Editor, and when one is preferred to be used over another. List the ones that are deprecated, as user may still see those in some old code.

There's the StandardMaterial and ShaderMaterial. BasicMaterial was removed in Engine v2.0.

ShaderMaterial has a tutorial here: https://developer.playcanvas.com/tutorials/custom-shaders
And core docs are here: https://developer.playcanvas.com/user-manual/graphics/shaders/

StandardMaterial support in the Editor is here: https://developer.playcanvas.com/user-manual/assets/types/material/
General docs on it are here: https://developer.playcanvas.com/user-manual/graphics/physical-rendering/

So anything still need doing here?

The shader material tutorial is buried in the list of random topics. But even then, there should be a section that talks a little about materials (what is supported and what is not, what kinds of them are there) in the user manual section. Perhaps under assets. For example, there is also pc.Material() here: https://developer.playcanvas.com/user-manual/assets/types/shader/ How would one know what is it?
