LineArt: Make consistent with master typo fix.

Fix T88464: Incorrect baking with camera markers.

Cleanup: Fix naming changes.

Remove the string value from attribute socket.

Attribute sockets should come in varieties for basic data types (float,
vector, etc.) instead of a string. Existing attribute layers should be
accessed explicitly with a "Read Attribute" node (todo).

Typed attributes for basic data will do broadcasting eventually.
This will allow connecting singular value sockets to an attribute input
without the need for a "Fill" node and perform basic broadcasting.

Add a new socket type for attributes.

The default_value is a string, as it will basically behave like a string
socket with some additional management in geometry nodes.

When used as an output the attribute should be generated automatically.
Auto-generated attributes should be removed automatically as soon as all
using nodes are done reading them.

LineArt: Use BVH for intersection calculation.

GPUMaterial: Add recalc flag workaround

Recalc flag on Material ID being unavailable to render engine, this
adds a simple way to detect material update by detecting shader creation
or update.

GPUNodeTree: Add weight tree inversion

This constructs a "mirror" nodetree that feeds the closure "shader"
nodes with their respective final weight.

The tree is mirrored using simple math nodes. This is quite messy but
this is the only way to proceed without introducing special nodes.
The other issue with this method is that inputs are all uniforms even
for unplugged socket on temporary math nodes with add bloat to the
shader uniform buffer structure.

Only the part relevant to the weighting is duplicated. Other connexions
with the shading tree are reuse.

All shader nodes are updated to receive a `Weight` hidden parameter.

The original shader mixing tree is preserve to let the choice of using
either way to weight the output.

For now this is only done for the output nodes. This will need to be
extended to Closure to RGBA sub-tree.

Manual scaling.

Dynamic api switching.

Cycles X: Experiment with tile reschedule heuristic

The idea is to add new tiles for rendering when the GPU starts to feel
hungry (as opposite of previous logic which was adding new work tiles
once the number of paths goes below certain threshold). Some motivation
behind this decision:

- There is only that many threads the GPU has. Having much more active
threads might avoid some scheduling latency, but there is limit to how
much it helps.

- Scheduling new tiles early on might have negative effect on coherency,
so allowing more paths to be terminated before re-scheduling keeps the
wavefront more coherent and efficient to be calculated.

The new code will use maximum number of threads the GPU has.

GPUNodeTree: Move closure socket implicit cast to ntreeGPUMaterialNodes

This reduces complexity of weighting closure in further dev.

GPUNode: Remove ssr_id and sss_id

These are not useful anymore.
