This add a new set of (possible) render settings that can be defined at
the scene level and overridable at the scene layer level.
Once we get workspaces we can either add workspace inbetween scene and
scene layer evaluation. Or to replace layer settings, to avoid extra
confusion to users.
An example of this setting is "samples", as implemented now for the clay
engine.
This fix doesn't really fix the situaion now because at the moment we
only flush the evaluated flags at DEG_OBJECT_ITER time, which is silly.
But it's all we can do until we have CoW.
So the parent visibility flag is not flushed. And even if we flushed its
visibility flag, we would need to rely on having the parent flag flushed
before we get to the object in question.
Anyways, take this commit as a future fix for when depsgraph comes to
rescue all our souls.
This implements weight rendering with the draw manager, with all drawing
options (Shading, wire, face masking, vertex masking).

Note: We should test if the armature is the "armature modifier" parent of the
object.
If any good samaritan feels like tackling this, the function to change
is: DRW_pose_mode_armature
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.
Needed to remove old draw code entirely.
Object mode selection support, pose and armature still need to be added.
Enabled when 'use_modern_viewport' is set.
Was performing context access per object for scene, region etc.
While not very slow they don't change during drawing so cache in a struct.
This also makes it possible to draw in views besides the current context.
Same as MEM_SAFE_FREE macro,
checks for NULL, runs free then sets NULL.
Blocks of code that do this many times are noisy and likely
errors here wouldn't be noticed immediately.
Also NULL's static vars which were being left set.
This removes MAX_STORAGE, MAX_BUFFERS, MAX_TEXTURES, MAX_PASSES limits.
Actual memory saving isn't so important, it just means we don't need to
manually bump these based on changes to engines.
Objects that were using the same lamp data were having the same display matrices.
This is fixed by allowing engine to store a memory block inside the object itself.
First this replace a custom data struct with IDProperty, and use
IDProperty group merge and copying functions. Which means that a collection
property setting is only created if necessary.
This implements the "Layer Collection settings" override system, as
suggested in the "Override Manifesto" document.
The core is working, with Scene, LayerCollection and Object using a
single IDProperty to store all the render settings data. Next step is to
migrate this to depsgraph.
Note: Clay engine "ssao_samples" was hardcoded to 32 for now. It will come
back as part of "Workspace Settings" later.
Many thanks for Bastien Montagne for the help with the UI template
nightmare ;)

Removed infinite details and went for decreasing details with the distance instead (like the axis aligned ortho view auto sized grid).
Separate drawing of the Z axis into 2 pass (using shading group) to render ordered transparency with the main grid pass.
We render selected meshes into another buffer and use a screen space shader to expand the color out of the mesh silouhette.
Pros: only one additionnal render pass is needed (like old outline code), and we have occluded informations.
Cons: memory usage is a problem. This method needs 2 color buffer to ping pong when expanding the outline and 1 depth buffer to test occluded fragments. This gives a 88 bits/pix memory footprint.
Idea: Since we don't need all color range but only some uniform colors (theme colors) we could manipulate only the color ID instead of the whole color this could cut the color buffer size and lower the memory footprint to 58 bits/pix.
