Replace tot/amount & size with num, in keeping with T85728.

Follow conventions from T85728.

The acquire locking of the draw manager introduced other issues.
The current implementation was a hacky solution as we know that the
final solution is something totally different {T98016}.

Some drivers completely forbid quote characters even in unused
preprocessor directives.
This patch adds a debug build check for all `.glsl` files that need to
be manually handled. For shared headers with `#include` directives, we
need to do runtime patching of the source to remove the quote.
Also fix an instance of the quotes check failing in `eevee_next`.

This was caused by the `Closure` members being added to the final contribution
more than once. The workaround is to clear the members once a closure has
been added to the final contribution. I used `inout` on `Closure` inputs
so that the render engine implementation of mix and add closure nodes
can do its own thing. The nodegraph handling of inout was changed for this
to work.

Curve tangent was correctly mistaken with curve normal.
This patch fixes the name of the output in the glsl function and make curve
attributes more explicit (with `curve_` prefix).
This also improve the normal computation by making it per pixel to match
cycles.
Also ports the changes to eevee-next.

Write to arrays directly instead of using the "step" utility.
|
|
Those settings are intended to be removed at some point, but for now they
are still needed because the radius attribute isn't supported.

The mesh drawing code used a different mesh to check whether or not to
draw face dots and to actually retrieve them. The fix is moving the
responsibility of determining whether to use subsurf face dots to the
creation of `MeshRenderData` where the mesh used for drawing is
known, rather than doing it at a higher level.

This was leading to linking errors.

This was because the alpha clip thresholding was previously done in the
material nodes codegen. Now it is the responsibility of the engine to
implement it.
This adds a loose uniform that is set by EEVEE itself to control the clip
behavior.

This was because the evaluation was still being deferred just like for the
opaque case.

When resizing a viewport all engine instance data was cleared.
This wasn't the intended design and lead to performance regressions
in the image engine.
This patch makes sure that the instance data isn't cleared when
the viewport size changes. When using instance data, draw engines
are responsible to update the textures accordingly.
This could also reduce flickering/stalling when resizing the viewport
in eevee-next.
Fixes T95428.

Recently `gpu_shader_3D_smooth_color_frag.glsl` had the uniform declarations removed.
For shaders without `ShaderCreateInfo` that require this source this results in the error:
```
ERROR (gpu.shader): hair_refine_shader_transform_feedback_workaround_create FragShader:
|
54 | fragColor = finalColor;
|
| gpu_shader_3D_smooth_color_frag.glsl:5:0: Error: Use of undeclared identifier 'fragColor'

55 | fragColor = blender_srgb_to_framebuffer_space(fragColor);

```
So port that shader to use `ShaderCreateInfo`.

The coarse polygon count was set to the one of the BMesh instead of
the the one of the mesh used for subdivision, which caused the
compute shaders to output wrong data.

Overwriting UV map or vertex color data in Geometry nodes will move the
layers to another CustomData channel, and as such, will make attribute
lookup fail from the UVMap and Vertex Color nodes in EEVEE as the
CustomDataType will also be modified (i.e. no longer `CD_MTFACE` or
`CD_MCOL`).
As discussed in T93179, the solution is to use `CD_PROP_AUTO_FROM_NAME`
so that the render engine is able to find the attributes. This also makes
EEVEE emulate Cycles behaviour in this regard. `attr_load_uv` and
`attr_load_color` are also removed in favor of the generic attribute
API in the various GLSL shaders.
Although `CD_PROP_AUTO_FROM_NAME` is now used even for UV maps, the
active UV map is still used in case the attribute name is empty, to
preserve the old behavior.

The crash is caused as the data for the UV editor is requested before
the data for the mesh as a separate draw update. Since building the UV
stretch angle buffer requires the position buffer, the latter is not
created yet in this case.
To fix this, create a local position buffer from the subdivision data. An
alternate fix was considered to remove the dependency on the position
buffer by interpolating on the GPU the coarse stretch angle buffer but
this did work. Maybe this will be revisited.

This commit introduce back support for all geometry types and all nodetree support.
Only the forward shading pipeline is implemented for now.
Vertex Displacement is automatically enabled for now.

This had only one use and it was for debugging. Remove the shader for now.
This also simplifies the debug drawing even if slower.

Some old compiler do not like this character even if inside an `#error`
directive.
|
|
Those are usually not supported but some driver silently fix them and most
just silently fail (rendering error).
|
|
This removes the usage of `GPU_shader_create_from_info_name()`.
