This implements weight rendering with the draw manager, with all drawing
options (Shading, wire, face masking, vertex masking).

Previously, every RenderPass would have a bitfield that specified its type. That limits the number of passes to 32, which was reached a while ago.
However, most of the code already supported arbitrary RenderPasses since they were also used to store Multilayer EXR images.
Therefore, this commit completely removes the passflag from RenderPass and changes all code to use the unique pass name for identification.
Since Blender Internal relies on hardcoded passes and to preserve compatibility, 32 pass names are reserved for the old hardcoded passes.
To support these arbitrary passes, the Render Result compositor node now adds dynamic sockets. For compatibility, the old hardcoded sockets are always stored and just hidden when the corresponding pass isn't available.
To use these changes, the Render Engine API now includes a function that allows render engines to add arbitrary passes to the render result. To be able to add options for these passes, addons can now add their own properties to SceneRenderLayers.
To keep the compositor input node updated, render engine plugins have to implement a callback that registers all the passes that will be generated.
From a user perspective, nothing should change with this commit.

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).
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.
We can now use object and other modes on top of Cycles.
Since we are now always on "render_to_view" (old Rendered mode), the
pause button is always visible.
- Unify GPUMaterial creation (world/mesh).
- Support for multiple shader variations (not used for now).
- Convert GPUInputs to DRWUniforms to be used with the draw manager.
- Nodetree Update is not supported. The only way to refresh the shaders is to change render engine.
- Cleanup in GPUPass.
- Add new temporary Node Compatibility type. Compatibility types should be removed in the future.
Now we just iterate over all objects. It may be a better idea to use a
smarter approach for performance. However, since this function is not
called regularly (only when changing Alembic file paths), it's not a very
big deal.
The original code was failing because the base to object flushing was
only happening as part of the depsgraph. However we can use the
evaluated values to set the initial values of the base.
In this particular case, we couldn't set the new object visible because
its selectability flag was not set yet.
Pending: Include the set in the rna depsgraph.objects
In fact it would be nice to unify them both. However this will likely
change once Depsgraph incorporate this iterator, so I'm not sure we
should bother with that.
