GPUBatch: Bypass empty drawcalls

These should be taken care of at a higher level but it's not
always possible. So it's still nice for cleaning up
captures in renderdoc.

Object Mode: Fix/Cleanup LightGrid overlays

Cleanup: DRW: Make drawcall render control flow a more easier to follow.

Workbench: Fix Shader compilation

DRW: Port Workbench to use DRWObjectInfos ubos

DRW: Make Call matrices and object infos into their own containers

This is in preparation of some bigger refactor that will put all
object matrices and infos into UBOs.

So this commit introduce a bit of performance penalty but it will
be claimed back!

DRW: Use ARB_shader_draw_parameters when available

This is to pass the offset of the object data to the shader
without a uniform call.

DRW: Use Model Matrix UBO blocks when possible

This bind the correct UBO block and pass the id inside the block
using a single int uniform.

There is still a legacy path for shader not using the modelBlock

GPencil: Use custom obmat instead of common_view_lib

DRW: Use new GPUDrawList to speedup instancing

This improves the performances of random instancing even further.
Test 30K objects:
42 fps -> 52 fps
24 ms -> 19 ms

DRW: Add builtin uniform to get full DRWResourceHandle from shader

This solves the issue with loosing outline around meshes that have
the same ID. Now it needs to have 16K objects in the scene for that to
happen.

Workbench: Simplify / Speedup Material Hash

This is negligeable speedup.

DRW: Add DRW_shgroup_uniform_vec3/4_copy

This will allow to remove a lot of temporary storage.

Workbench: Use resource_id instead of own index

This only modifies the shader and should not create real improvement.
However, this makes it possible to reduce shgroups count drastically
when outline rendering is enabled.

Cleanup: Wireframe: Use vec3_copy and remove unused code

DRW: Replace DRW_CALL_OBINFOS by a boolean in DRWManager

This is to remove the use of keeping a shared flag per drawcall.

DRW: Fix Batch key bitshifting
