[NGRM] - Option to render layers in ortographic view superimposed, honoring layer ordering instead of z values

[nilscb]

Example all of wells on top of a map.

This will replace the current functionality of turning of and on z-buffer depth test for each layer ("depthTest" true/false keyword) which is not optimal for true 3D layers like the grid layer and the wells layer.

Some possible useful discussion/links on how to implement: https://github.com/visgl/deck.gl/issues/3313

@nilscb can we rephrase this as a use case and leave the suggested implementation as a detail (there might be other ways to achieve the same goal)?

Eg. "Option to render layers in ortographic view superimposed, honoring layer ordering instead of z values"
