This commit removes all EEVEE specific code from the `gpu_shader_material*.glsl`
files. It defines a clear interface to evaluate the closure nodes leaving
more flexibility to the render engine.
Some of the long standing workaround are fixed:
- bump mapping support is no longer duplicating a lot of node and is instead
compiled into a function call.
- bump rewiring to Normal socket is no longer needed as we now use a global
`g_data.N` for that.
Closure sampling with upstread weight eval is now supported if the engine needs
it.
This also makes all the material GLSL sources use `GPUSource` for better
debugging experience. The `GPUFunction` parsing now happens in `GPUSource`
creation.
The whole `GPUCodegen` now uses the `ShaderCreateInfo` and is object type
agnostic. Is has also been rewritten in C++.
This patch changes a view behavior for EEVEE:
- Mix shader node factor imput is now clamped.
- Tangent Vector displacement behavior is now matching cycles.
- The chosen BSDF used for SSR might change.
- Hair shading may have very small changes on very large hairs when using hair
polygon stripes.
- ShaderToRGB node will remove any SSR and SSS form a shader.
- SSS radius input now is no longer a scaling factor but defines an average
radius. The SSS kernel "shape" (radii) are still defined by the socket default
values.
Appart from the listed changes no other regressions are expected.
So far it was needed to declare a new RNA struct to `RNA_access.h` manually.
Since 9b298cf3db we generate a `RNA_prototypes.h` for RNA property
declarations. Now this also includes the RNA struct declarations, so they don't
have to be added manually anymore.

Along with the general changes to CPP this commit does the following
- Use static casts where possible
- Use new CPP MEM library functions instead of cast
- Use listbase macros where possible
- Declare variables where initialized

The original move to c++ that the other commits depended upon had some issues
that should be fixed before committing it again. The issues were reported in
T93797, T93809 and T93798.
We should also find a better rule for not using c-style casts going forward,
although that wouldn't have been reason enough to revert the commits.
Introducing something like a `MEM_new<T>` and `MEM_delete<T>`
function might help with the the most common case of casting the return
type of `MEM_malloc`.
Going forward, I recommend first committing the changes that don't
require converting files to c++. Then convert the shading node files
in smaller chunks. Especially don't mix fairly low risk changes like
moving some simple nodes, with higher risk changes.
Error in d5efda72f5. Was changing an iteration that would free items
to an iterator that is not safe for use in such cases.
There still seem to be significant issues with the rendering, but that's
a separate issue to be fixed.
- Added space below non doc-string comments to make it clear
these aren't comments for the symbols directly below them.
- Use doxy sections for some headers.
- Minor improvements to doc-strings.

This will be useful in the future to use the new socket builder API
Aditional changes:
- Declare variables where initialized
- Do not use relative includes
