GPv2 used the depth buffer at the end of a stroke drawing operation to project points and interpolated between detected values. This does not work in GPv3 because the strokes are added directly to drawings. Depth projection has to happen continuously, updating points between the last depth value and the next when a new hit is recorded.
Resolves#125258.

`GPENCIL_draw_scene` uses `pd->tobjects.first == nullptr` to determine
whether to early return (draw nothing). When there's only "In Front"
grease pencil objects in scene, `tobjects.first` can be `nullptr` but
`tobjects_infront.first` is valid, in which case no grease pencil would
be drawn. Becase `gpencil_object_cache_sort` will link those two command
lists both to `tobjects` and allow `infront` ones to draw after others,
thus move it before the early return to allow drawing to proceed
normally.

`object_is_paint_mode()` returns true for objects that are not in active
interaction mode. This results in drawing of overlays for each Grease
Pencil object. Now fixed with adjusted condition.

The code relied on `disable_depth_test` to render without depth testing
on selection, but it was set at pre-draw, so it was always false when
calling `res.select_bind` inside the sync code.
There was also no code to tell in-front and regular objects apart, so
in-front objects were not prioritized.
The previous engine seemingly divided the depth of In Front objects by
100, so I'm reproducing the same behavior here.

Visibility test is not setup correctly and only tests positives. This
test should be adapted with better testing. For now we skip the test.
Resource id test was wrong as it didn't add the null resource for
drawcalls with no handle. Ref `DrawCommandBuf::generate_commands`.

Prevents creation of Bezier curve's `IndexMask` when it is not needed.
It was created on every request, even when `CurvesBatchCache` was valid.
Also prevents redundant initialization of `GeometryDeformation`.

Overlay engine rendered the editor background incorrectly when no image
is present. It used to render an alpha checker background indicating
that an image was present. The cause for this was that the in front
depth texture was attached, but isn't used at all.
The second change is that the image prepass should only be drawn when
there is an image present in the image editor other wise external the
prepass would alter the depth texture indicating that there is an image
present.

This creates more boilerplate code, but it's easier to extend,
it's follows the same structure as the mesh extraction, and
it's more aligned to planned future performance improvements.

Was missed in the move to Overlay Next.
Now bring it back in `class Axes: Overlay`
Thx @pragma37 making me aware chaging draw state (not writing depth)
can be done using a subpass!

The new description for `bNode.type_legacy`:
```
/**
* Legacy integer type for nodes. It does not uniquely identify a node type, only the `idname`
* does that. For example, all custom nodes use #NODE_CUSTOM but do have different idnames.
* This is mainly kept for compatibility reasons.
*
* Currently, this type is also used in many parts of Blender, but that should slowly be phased
* out by either relying on idnames, accessor methods like `node.is_reroute()`.
*
* A main benefit of this integer type over using idnames currently is that integer comparison is
* much cheaper than string comparison, especially if many idnames have the same prefix (e.g.
* "GeometryNode"). Eventually, we could introduce cheap-to-compare runtime identifier for node
* types. That could mean e.g. using `ustring` for idnames (where string comparison is just
* pointer comparison), or using a run-time generated integer that is automatically assigned when
* node types are registered.

The material index in Grease Pencil attributes can be negative, since they are a
generic attribute. The shader, however, requires clamping of the material index
to avoid an invalid lookup. This was already happening for the material buffer
setup (`grease_pencil_object_cache_populate`), but not for the actual VBO.

When no image is present the depth and color buffers aren't correctly
cleared, resulting in showing the previous buffers.
Replaced the clear on bind with regular clearing operations.

UnitSettings::scale_length was used to scale reported
values for operators (translate, shrink-fatten, voxel-size).
This isn't expected as the value isn't editable when the unit-system
is set to None.
Add BKE_unit_value_as_string_scaled utility function for clarity &
to ensure scaling is only applied when it should be.
When using clangd or running clang-tidy on headers there are
currently many errors. These are noisy in IDEs, make auto fixes
impossible, and break features like code completion, refactoring
and navigation.
This makes source/blender headers work by themselves, which is
generally the goal anyway. But #includes and forward declarations
were often incomplete.
* Add #includes and forward declarations
* Add IWYU pragma: export in a few places
* Remove some unused #includes (but there are many more)
* Tweak ShaderCreateInfo macros to work better with clangd
Some types of headers still have errors, these could be fixed or
worked around with more investigation. Mostly preprocessor
template headers like NOD_static_types.h.
Note that that disabling WITH_UNITY_BUILD is required for clangd to
work properly, otherwise compile_commands.json does not contain
the information for the relevant source files.
For more details see the developer docs:

Mistak in 39f7c506b5.
The VBOs need to be allocated! And we can just use a single dummy
type as well, rather than using the type from the attribute request
which is meaningless in this case.
Only draw relationship lines between a constrained object/bone and its
target when there is actually a valid target. Previously Blender would
always draw a line, which would go to the world origin when the
constraint has no target. This was visually rather noisy and potentially
even misleading when there is actually an object at the origin.

This caused build errors on the docs builder, I can't seem to reproduce
locally, so revert for now and have another look at some point in the
future.
Sadly as these changes usually go, this took 5c515e26bb and
2f0fc7fc9f with it as well.
