Move GPU compositing out of draw-manager off-screen drawing

Also no need to use VP_legacy_ prefix here.

Cycles: Fix OpenCL compilation failure after recent color changes

It is really confusing to have some functions available in some devices
and not on another devices.

Cleanup: move off-screen drawing to view3d_draw.c

Since offscreen drawing now uses draw engine, this doesn't need to be
considered legacy.

Note that there are some calls into view3d_draw_legacy.c from view3d_draw.c
this is generally not accepted, so its only dont where there are checks
for new/old engine.
Functions exposed to do this use a VP_deprecated prefix.

Draw Manager: Enable Pose engine as part of the weight paint mode

We still need to bring pose bone drawing for the pose engine.

Note: In the future, once we get face-widget selection, we will need to
make sure the pose engien only draws then if "weight paint mode" is not
enabled too.

Draw Manager: Fix pose mode not working well.

In the future this will allow us to implement things like face manipulators.

For now however, this is getting on the way of using pose mode
(mesh objects are drawn green).

NOTE: pose engine should also be the one taking care of pose bones

(and for that matter, X-Ray armature option should/could be a property
of the Pose engine even).

Cycles: Use render visibility for duplis when Render Layer option in viewport is used

Previously the logic was different for duplis and regular objects: regular objects
were using render visibility when Render Layer option is enabled which duplis were
always using viewport visibility when rendering from the viewport.

This was quite confusing because caused different results in viewport and render
when artists were expecting them to match 1:1.

Fix draw manager w/ cycles

8b2640f08 introduced the error,
caused by external-engine needing depth mask to be disabled,
which happened to be the case before changing state changing logic.

Eevee: Fix Lamp Roughness.

GPUMaterial: Force old outputs to fail with EEVEE.

Workaround waiting for compatibility bit / or PyNodes.

NodeTree: Add eevee default shader tree.

Eevee: Add "uber" Shader Output Nodes.

Include Metallic and Specular workflow.
Clearcoat and are not implemented yet.

Draw Manager: Introduce a foreach function for all shgroups in a pass.

Validate collection properties at readile

The alternative would be to do version bump + doversioning every
time a new property is added.

Make IDP_MergeGroup recursive

With this we also do not need IDP_MergeGroupValues anymore.
If this causes problems in the future we can always make recursion an
option (like overwrite is).

Cycles: Simplify code in SVM image by using new utility function

Can not measure any performance difference, so seems the code is identical
and just shorter.

Cycles: Add utility function to convert float4 color from srgb to linear

It will use SSE2 optimized version when is possible.

Fix crash loading files where outliner treestore isn't set

Add BBone and Wire Armature draw types to DrawManager.

Most of this was copying/adapting code from octahedral existing draw
code, tough part was to get BBone matrices to behave as expected, they
are using a fairly specific setup...

Addresses T51365 and T51362.

Draw Manager: fix draw-state switching logic

Changing states didn't properly reset between shading groups
causing the GL state to be wrong based on draw order.

States are now only set when changed.
