DRW: Instance selection id: use Batch buffers instead of DRWInstanceData

This is motivated by the refactor of DRWInstanceData to be actual non
contiguous mempools.

Eevee: Add support for the Hair info node.

Only the random output is not supported for the moment.

Eevee: Add support for new Hair geometry system.

This now can shade actual poly strips that mimics cylinders.
This makes hair coverage exact compared to the line method and result in
smoother fading hair.

This does make the sampling a bit more exact but needs more samples to
converge properly.

GPUMaterial: Add support for hair vertex color, uvs and orco.

DRW: Add new GPU hair system.

This new system use transform feedback to compute subdivided hair points
position. For now no smoothing is done between input points.

This new system decouple the strands data (uv, mcol) with the points
position, requiring less update work if only simulation is running.

In the future, we can have compute shader do the work of the feedback
transform pass since it's really what it's meant to. Also we could generate
the child particles during this pass, releasing some CPU time.

draw_hair.c has been created to handle all of the Shading group creations
as well as subdivision shaders.

We store one final batch per settings combination because multiple viewport
or render could use the same particle system with a different subdivision
count or hair shape type.

Cycles: Use new internal hair shape properties.

The do_version actually copy the existing custom properties to the internal
ones, because theses properties are straight port from cycles.

Hair Particles: DNA: Add properties for new GPU hairs.

Hair Particles shape properties are ported from cycles. Thoses properties
have the same defaults and have a do_version of their own. Cycles will use
theses properties instead of its custom ones.

Some realtime engine specific settings are also added to scene->r because
it's much easier to control as global values.

Bumping Version number so cycles can do its own do_version on top of the
default settings.

DRW: Add new per drawcall option to bypass culling.

GPUTexture: Add support for GL_RGBA16 texture format.

DRW: Add DRW_CALL_PROCEDURAL DRWCall type.

This mimics the behaviour of DRW_shgroup_empty_tri_batch_create and will
replace it eventually.

The advantage is that it's compatible with transform feedback.

BLI: Utils: Add Macro that compute the number of digits in integers type.

Usefull if you want to create char chains to contains hashes of a certain
type.

Keymap: add back sculpt keys

Shouldn't have been removed in recent keymap edits.

Cleanup/fix wrong modifiers targets handling in COW context.

Modifiers stack only get COW/evaluated IDs, so no need to go auery again
DEG for those. Further more, now unified handling of EditBMesh case (was
done on case-by-case basis in a few modifiers, not all for some reason).

We are still missing the ability to get final and cage deformed meshes
when in Edit mode though, this is to be defined/implemented in depsgraph.

Depsgraph: Add TODO about backing up evaluated state of ID

Add deformed evaluated mesh to object

This is a first step to have correspondence of legacy derivedDeform
within a new formulation. Only base ground for now to support file
reading, copy-on-write remapping and such.

Fix T55253: Camera lens can't be edited after keyframing it

Bring back animation channel exception for tag flag=0.

Cleanup: Wrap object runtime eval members into own struct

Outliner: support toggling non-active edit/pose mode objects

Support switching non-active objects in/out of a mode from the outliner.

- This allows users to change which objects are in a mode w/o
having to exit the mode and change seleciton.
- Changing the mode of the active object applies to all other objects.
- By convention setting a mode selects, removing de-selects,
this is done for convenience so switching to a mode from object mode
maintains the set of objects in the current mode.

See: T55246

UI: Show outliner icon highlight w/ non-active edit-mode objects

BKE_object: Add BKE_object_data_is_in_editmode
