Initial review of the shard shadows in the workbench engine.
Speed optimizations like transform feedback are not implemented yet. I first want this part to be reviewed and merged.
@fclem please check the note in drw_stencil_set it was holding back nequal == 0 as by default DST.stencil_mask was set to 0. questioin is should we remove the whole check or not.
Also I am still looking for a better name (or split the enum) for DRW_STATE_STENCIL_DEPTH_FAIL_INCR_DECR_WRAP

Normal packing. The sign is stored in the A of the color buffer.
if the A == 1.0 the normal should be inverted. before use.
The reason is that packing has more precision for frontfaces, than for
backfaces
Added Object Overlap Overlay
- Added R32UI support to GPU_framebuffer
- Added R32U support to draw manager
- The overlay mode has a object data pass that will render 'needed' data to specific buffers so we can mix them together via a deferred rendering. In future will also add UV's and other data
- Overlap is implemented as an overlay so it could be used on top of the Scene lighted Solid mode (that will be rendered by Eevee.

Similar materials will reuse the same shadergroup. Currently using
a custom hash function that might select too similar colors into the
same material.
Reintroduced the workbench_materials.c this file will be responsible for
material lookup/creation and shader compilation
Fixed a GPUShader mem leak
Currently uses static lighting. Will become HDRI lighting.
Added do_versions to set default drawtype_solid and drawtype_texture to
OB_LIGHTING_STUDIO. When View3D space is created drawtype_solid and
drawtype_texture are also set to OB_LIGHTING_STUDIO.
Current studio lighting uses a dot product to simulate static lighting.
Will need to be changed in the future with different lighting models.
- added the drawtype_solid, drawtype_wireframe, drawtype_texture to
View3D
- enabled workbench panels for important render engines
- merged workbench_materials to solid_flat_mode. All draw modes will get
its own fast implementation in the workbench
