Overlay Engine: Armature: Bone selection overlay

I forgot to implement this back

GPU: Remove The use of geom shader for dashed lines

Use the same trick used in overlay engine.

Also fixed some undefined behavior with missing viewport uniform in some
calls.

Cleanup: Remove more unused files

Cleanup: Remove older draw engine from draw module

GPU: Batch: Add second instance buffer

This is needed in one corner case. In an attempt to get rid of geometry
shader, we need to use instancing using pos and lnor vbos for edit mesh
normals overlay.

This is a bit hacky and quickly made. This should be do more thoroughly.

Cleanup: Make empty image use quad batch instead of specific batch

Cleanup: DRW: Remove old unused code

Cleanup: GPU: Remove unused shaders

Overlay Engine: Edit Mode: Change Normal overlays

This gets rid of the geometry shader for normal display.
(note: happens to be twice as fast)
This also remove the unecessary shader variations.

Another goal was to get the do_zbufclip behavior back.
We occlude the base vertex which can occasion some flickers bu

Overlay Engine: Edit Mesh: Port Occlusion detection to shader

This moves the occluded wire fading at the edit cage drawing, thus removing
the need for a fullscreen compositing pass.

Cleanup: Port back the custom shape ghash to revert perf regression

Using the DRW instancing is much slower because the modelmat ubo is too
small to contain many obmat of the same GPUBatch type.

Cleanup: Remove stipple start position duplication

Removes 3 floats per stipple vert. Using the same technique we could
remove the need for geom shader for GPU internal shader shader.

Overlay Engine: Loose Edges/Verts

Merge branch 'master' into tmp-overlay-engine

Overlay Engine: Fix background image and sort empty images by Z depth

Overlay Engine: Sculpt Mask

Overlay Engine: Particles

Overlay Engine: Paint Modes

Overlay Engine: Lattice

Cleanup: Port lattice wireframe coloring to shader

Overlay Engine: MetaBall

Note: This also improve handles positioning using the armature point shader
